Macos Catalina Clean Reinstall

I'd like to reiterate this. I just updated to 10.15.5 on Friday and my 2017 MacBookPro 13' has been crashing every single day since. It's not as bad as the crashes I experienced in early April, two updates back. My Mac was basically bricked for a few days. But to have this happening now again is absolutely intolerable.

Reinstall Macos Catalina Without Internet

I’m now trying to reinstall Mac OS Catalina, but the installation keeps crashing while downloading. Moreover, after crashing for the first time while trying to reinstall Catalina, the lock screen buttons colour turned turquoise blue and the recovery mode doesn’t detect users anymore on the Mac to recover from.

How can you guys release such unstable updates like this? I've been a an Apple user since 1986 and never had such bad instability issues. The quality control is terrible. I don't have another computer for my work. Please issue a fix to prevent theses crashes from continually taking place. Catalina is terrible.
