snapd doesn't uninstall programs

Ubuntu 22.04, snap, Dell G5 laptop.

When installing software with snap (or ubuntunsoftware) it install them, but after a while everything freezes and crashes. When I try to remove and install again, it said that is removed but program still runs. I can find fractures and whole installations in /snap/ folder and (depending on app) rm -r works on removing them. But even then, there are some fractures in roots and elsewhere (often sub snap directories). It's like hydra, you kill one thing but it spawns in multiple directions.
