The install process is the same. I just wiped out my templates, redownloaded and reinstalled on 2.91.0, and I'm not having issues, I'm downloading 2.93 now to test that, too.
I'm on a Windows 10 PC, I haven't yet tested on Mac and Linux for compatibility. I'll let you know if I can replicate the crash on my end.
Funny enough, Blunder has an init (startup script) that could potentially give issues on startup, but I haven't added one to BLUI yet, so maybe there's something there.
