I updated to 2019.3.0f1 today and the editor is completely plagued with crashes. I was already getting multiple crashes per day with betas 8 through 10. Not only has this not improved for the release candidate, it has gotten far worse. And what compounds this problem is that the bug reporter doesn't pop up at all -- the whole thing just dies. I've been using Unity for over a decade, and have never seen such an unstable release, especially one that is supposedly in the release candidate stage. Editor logs show nothing. I deleted Library and re-imported. Literally the first time I tabbed into Unity afterwards and tried to press Play, it crashed to desktop. I'm not using SRP or DOTS or any fancy features. Just trying to use my project codebase, one that has been battle-tested since 2014 on multiple shipped titles. When I submit crash reports with my project attached, I get them closed as not reproducible. And this is not to mention the countless issues with the editor not properly having focus when I tab back in from Visual Studio, or spinning an hourglass every time I tab back in, unlike every previous version that has worked like a charm. I've used and championed Unity for over a decade because it has always represented the high water mark for speed of iteration and stability. This is very frustrating.
