Crash in flutter engine on macOS #148279
Description
Steps to reproduce
Unfortunately I don't have a simple reproduction step for this. There seems to be some kind of race condition initializing the flutter engine. Once in every several starts my app will crash while trying to enable semantics in the engine. I've tried wrapping my entire widget tree in an ExcludeSemantics node but this doesn't seem to help.
This is the last thing keeping me from releasing this app to production but so far I haven't been able to pin it down to any particular component or library.
A typical crash trace is as follows:
OS Version: macOS 14.4.1 (23E224)
Report Version: 104
Exception Type: EXC_CRASH (SIGABRT)
Crashed Thread: 0
Application Specific Information:
Semantics must be enabled.
