Quick answer: Leave gameplay nodes on the default Inherit/Pausable mode and set the pause menu's process_mode to PROCESS_MODE_WHEN_PAUSED so it keeps running while the tree is paused.

Godot's tree-wide pause is convenient but pauses your menu as well. The pause UI needs a process mode that explicitly keeps it active while the rest of the tree is frozen.

How to fix it

1. Set the menu to run when paused

On the pause menu root, set Process Mode to When Paused so it processes input and animation only while get_tree().paused is true.

2. Keep gameplay pausable

Leave gameplay nodes on Inherit or Pausable so they stop when the tree pauses, giving you a clean freeze of the simulation.

3. Watch nested process modes

Remember a child inherits its parent's mode unless overridden. Set the menu subtree explicitly so a pausable parent does not freeze your interactive UI.

Catching the ones you can't reproduce

The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.

Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.

This is where a tool like Bugnet earns its place. Its SDK captures every Godot error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.

Reproduce it once with full context and the fix writes itself. The hunt is the expensive part.
