If you are on pc, you may try a few console commands.
Some commands disable achievements, if that's what you're going for might need to restart the game.

Depending on the glitch, it may help to use the "kill" command or other teleports ("kill" may cause you to lose some items).
There is unfortunately one save per playthrough, so there is no way to recover old saves. You can create backups yourself, and there is a mod that makes this easier: https://www.nexusmods.com/subnautica/mods/76
