Quick answer: Godot 4 C# editor utility hanging on Godot.Engine.GetVersionInfo() during a long asset load? Engine queries are sometimes blocked - defer to main thread.
Asset loader logs version; logging hangs because the engine is mid-import.
Defer to main thread
CallDeferred(MethodName.LogVersion);Runs on main; engine state stable.
Or cache at startup
Read version once at editor open; use cached value. No mid-import queries.
Profile engine calls
Each engine call from worker thread is a candidate. Identify; eliminate.
“Engine state isn't thread-safe in all paths. Worker thread queries can block.”
Tool code that touches the engine should run on main thread. The pattern is project-wide.
