I've had problems with Visual Studio 2019 crashing when I installed build 2393 a few months ago, and I fell back at the time to using build 2389. I was checking to see if there was a new build to try today and I see on the archives page:
1) Prematurely, it should be available for download soon.
2) Yes. We think it's a much easier system to follow, for us as well. The old version still lives on as the VA_X.dll version, and is still used in some places internally.
Also, if you experience crashes please contact support. Crashing is not okay and if reverting fixed the issue for you we would love to know more.
Sorry, I never got around to reporting it. I will definitely try the new build when available and will update if I am still seeing problems with that version.
