For a few years, I’ve been experiencing random crashes in VS Code when saving GDScript files, and after a long time troubleshooting, I finally found the root cause.
The issue was that
ScriptEditor::reload_scripts
was being called directly on the language server thread whennetwork/language_server/use_thread
was enabled. This led to race conditions that would eventually cause the crashes.
