How do I prevent crash loops in my game?

Break the cycle that makes a crash repeat every launch. Make startup and recovery robust: handle bad states gracefully, and when the game detects it's failing repeatedly, recover by resetting to a safe state rather than re-entering the crash, since a crash loop happens when the game hits a bad state, crashes, then re-enters the same bad state and crashes again forever. Handle the corrupted data or condition that causes the loop, validate persistent data on load and recover from or reset bad data rather than crashing on it every time, since crash loops often stem from persistent bad state (a corrupted save, a bad config) that the game keeps loading and crashing on. And capture the crash from the field with context so you can see players are caught in a loop and what triggers it, and ship a fix or recovery that breaks it before more players are locked out. A crash loop locks the player out entirely, so making startup and recovery robust, handling the persistent bad state, and capturing the crash to break the loop are critical preventions.

What causes a crash loop?

A persistent bad state combined with the game re-entering it every launch or every attempt. The pattern is: the game loads or reaches some state that triggers a crash, but because that state is persistent, a corrupted save, a bad config, an invalid stored value, the game loads the same bad state again on the next launch and crashes again, repeating indefinitely. What makes it a loop rather than a one-time crash is the persistence: the thing causing the crash doesn't change between attempts, so each launch reliably hits it. Startup crash loops are especially common because startup loads persistent data (saves, configs, settings) and if that data is corrupted or invalid, every launch crashes on it. The same can happen at a specific point if the game keeps trying to reach a state it can't handle. Preventing crash loops means breaking this cycle: validating persistent data on load and recovering from or resetting bad data so the game doesn't keep crashing on it, and making startup and recovery robust so that when repeated failure is detected, the game resets to a safe state rather than re-entering the crash. Capturing the crash from the field helps you identify what persistent state is causing the loop so you can handle it.

Why are crash loops so bad?

Because they lock the player out of the game entirely, with no way in. A normal crash is frustrating but the player can relaunch and continue; a crash loop crashes every time they try, so they simply cannot play, the game is completely inaccessible to them until you ship a fix. This is the worst possible outcome for an affected player: they've lost not just a session but access to the game itself, often along with their progress if the loop stems from a corrupted save. It tends to affect every player who hits the triggering condition consistently rather than intermittently, so an affected player stays locked out, and it frequently happens at startup (where it prevents the game from ever opening) or after an update (where it can lock out players who were previously fine). The combination of total loss of access, consistency, and the player's helplessness, there's nothing they can do, makes crash loops uniquely damaging and uniquely enraging, driving uninstalls and harsh reviews. This is why they're critical to prevent through robust startup and recovery and handling of persistent bad state, and to fix fast by capturing the crash so you can break the loop before more players are locked out.

How to Prevent Crash Loops

Quick answer: Make startup and recovery robust so a bad state doesn't crash every launch, handle the corrupted data or condition causing the loop, and capture the crash so you can break it. A crash loop locks the player out entirely.

A crash loop, the game crashing every time the player tries to launch or reach a point, is among the worst bugs because it locks the player out completely. Preventing crash loops protects access to your game. Here's how to prevent crash loops.

Make Startup and Recovery Robust

A crash loop usually happens because the game hits a bad state on startup or at a point and crashes, then re-enters the same bad state and crashes again, forever. So make startup and recovery robust: handle bad states gracefully, and when the game detects it's failing repeatedly, recover, reset to a safe state rather than re-entering the crash.

Bugnet captures crashes with breadcrumbs, so you can see the state that triggers a loop. Robust startup and recovery prevent crash loops by breaking the cycle, handling the bad state gracefully instead of crashing into it again, so the player isn't locked out.

Handle the Corrupted Data or Condition That Causes the Loop

Crash loops often stem from persistent bad data, a corrupted save, a bad config, an invalid stored state, that the game loads, crashes on, and loads again. So handle the corrupted data or condition: validate persistent data on load, and recover from or reset bad data rather than crashing on it every time, since the persistence is what makes it a loop.

Bugnet captures crashes with context, so loops tied to bad data are identifiable. Handling the corrupted data or condition prevents the crash loops that come from persistent bad state, by removing or recovering from the thing the game keeps crashing on.

Capture the Crash So You Can Break the Loop

A crash loop locks players out, so you need to see it to fix it fast, capture the crash from the field with context. Seeing that players are caught in a loop, and what triggers it, lets you ship a fix or recovery that breaks the loop and restores access, before more players are locked out.

Bugnet captures crashes from the field with full context, so crash loops are visible and diagnosable. So prevent crash loops by making startup and recovery robust, handling the corrupted data or condition that causes them, and capturing the crash to break the loop, protecting players from being locked out of your game entirely.

Make startup and recovery robust so a bad state doesn't crash every launch, handle the corrupted data or condition causing the loop, and capture the crash so you can break it. A crash loop locks the player out entirely.
