Unity keeps crashing with "Fatal error in GC" in a popup as the title and "GetThreadContext failed" as the body. This has been rather sudden as has been working for months without problems. The last things done were updated Avast to version 8, but I already have Unity and my project added as exceptions in addition to that I've tried disabling Avast entirely. Does anyone have any idea what's going on? I can't work on my project but for a couple minutes before it happens.
