Apple has never understood the business need for compatibility and stability. We just call Catalina Apple's Vista. I have to keep a copy of Windows 10 on Parallels just to be able to support customers trapped on older version of FileMaker for technical reasons as I can't use my Mac for this.
I seem to be sending a lot of reports due to errors to Apple these days, just unplugging the USB C connection on my 2019 MacBook Air usually means a system crash and restart, my 2018 Air was the same.
