How do I roll back the game version?

I’ve installed a new edition (using Epic Games) and I’m not able to play any saved games… It is possible roll back the version or make saved games compatible with the new edition?

Thank you!

Don’t know about rolling back game version. Rolling back game version will void/remove whatever new dlc your suppose to get. It’s no big deal as far as I’m concerned, I just start a new game.
