I usually end up in need of redoing a fresh install until it breaks up again.
That’s common when you start adding random PPAs, running some commands without understanding (we all do 👀) and whatnot, but you can save yourself from reinstalling over and over by using an immutable distribution so at any point you will know what changed in your system and if it breaks you can just roll back to the previous working point and either fix your mistake or wait for a fix from upstream when an issue happens there (this year there were a few kinda major hiccups on Fedora for example).
I suggest you try one of the Fedora immutable spins (Silverblue, Kinoite, Sericea) or Vanilla OS, though I would hold off from it until Orchid comes out.
If you want to go all in you can use NixOS, but it takes a lot of reading
