iOS simulator ImageLoader startup crash on Catalina 10.15.2, Xcode 11.3

I am using Xcode 11.3 and did upgrade to Catalina 10.15.2 today. Everything was running fine before the upgrade and I can't think of anything else that would've caused this.


I've tried the typical, clean/build, delete derived data...but nothing has helped.


Has anyone else experienced issues with crashing when trying to run in the simulator? See attached image for callstack.

Had the same issue. It's related to the thread sanitizer in the simluator. Followed the instructions in this other post and this resolved the issue for me: https://forums.developer.apple.com/thread/126891

I just confirmed that the project runs fine on my non-Catalina system. This issue arised after updating to 10.15.2.


On non-Catalina system, I am running Xcode 11.3 and everything is fine.
