How to Uninstall Mac OS 15.8.2 & use an older version that doesn't have so many bugs?

I've just installed Mac OS 15.8.2 on my MacBook Pro with M1 Max chip. I'm experiencing bugs with the Finder that aren't going away & want to use an older OS version that doesn't have so many bugs. How can I go back to the version I had before if I'm using an external drive Time Machine?


Please advise.


Many thanks!
