You are destroying all mods ,and without them ,if you do make an update please repair that what from the first itteration has benn bugged hard ,while in idle the screen goes black and after a few minutes of gameplay crash to desktop.
Thank you.

Well, you don't have to update. I have not updated since I installed the game, because I didn't need to do it. Updates is mostly bug fixes and is not that important. If you enjoy playing with the current version of your game, I don't see why you would need to update.

My current version does not suport free camera arround 50% of my flawlessly working mods now do not respond i receive crash to desktop or does not load (NOT RESPONDING) evevry day ,ican`t roll back because my saves don`t work and i played more than 60% of the game,never ever happened to me on yhe other witchers 1 and 2,not even on 3 until now ,it`s a messy life i have the only thing that i liked very much are single players with a goood story ,i know i don`t have to update but i don`t have time to verify every mod i have in detail.
Have a nice day.

Sounds like you're using Galaxy.
You can change settings in Galaxy (not sure if it's per game) to stop automatic updating games.
You should also be able to do a rollback with Galaxy, though I've never tried it.

When was the last update, though?
