This started happening for me after I updated to Xcode 12 (using Xamarin and Visual Studio for Mac) and the latest Xamarin and After I changed the application icon via Assets.xcassets. I do see this in my screen dump farther down:
11 dyld_sim 0x00000001071ea14c ImageLoader::recursiveLoadLibraries(ImageLoader::LinkContext const&, bool, ImageLoader::RPathChain const&, char const*) + 346
I wonder if it has something to do with the spotlight icon for my app?
Edit: I just went to spotlight on the simulator - I see blank icons for my app (underneath the spotlight entry box). I clicked on one of them and my app opened. Then I closed all the running apps and went to spotlight again and I now see my apps icon. I then started my app in the debugger again and so far (about 10 minutes) no spotlight error.
