I had an issue switching away from Pop!, and it may have been a one off, but when I tried to install a different distro, and it wound up screwing up my boot partition to the point the easiest thing was just to run a live distro, pop open parted, and wipe from there before I could install a different distro.

Mostly mentioning it because it was annoying to figure out and remedy - the remedy was annoying because I only had one flash drive so I had to wipe what I wanted to install, and just wasting time regarding that.
