cant load my save game after uninstaling mods
some ideas?

I'm guessing that "reinstall the mods" is not the solution you're after?

mods does not exist on workshop anymore

Don't uninstall mods. :p

Once you use a mod in a savegame, it'll be referenced in that save unless you remove any instance where you have used it (IE sold off placed modded buildings, sold off all of that mod vehicle) before you save again and then uninstall them.

If you've uninstalled the mod before removing any instance of them in your savegame, the save will be calling for assets that are no longer present and crashes. There's nothing you can do to fix it except for reinstalling the mod.
