Resolution Note (2021.2.X):
This issue is caused by a changes made by Apple in the MacOS Catalina (11.0) SDK that restricts certain context methods that can be called in multi-threaded situations. In particular, the crash results from calling the context methods in a thread supporting a native OpenGL plugin (i.e., a custom .dylib not provided by Unity).
Running the Editor with `-force-gfx-direct` resolves these crashes and can be used as a temporary workaround.
The issue can be mitigated by updating native plugin implementations to avoid calling these context methods from a thread other than the main thread.
