Anybody else experiencing game breaking bugs right now?

Like I can't sell my stuff now, game will insta crash when I click on an item to sell, doesn't matter which character's backpack and doesn't matter if I barter or trade. Also, it takes like 5 minutes before the vendors items or cash appears.

Characters won't engage in combat at all and randomly. When I select them to engage an enemy, they teleport to another location and no matter what, they won't attack. It's like they are in another game entirely. I also can't switch back to the characters that are in the fight.

Lot's of freezing too. I have to save scum before entering any convo now as it might just lock me out of any action for 30 minutes or straight up crash. And my charisma Shadowheart is useless now since it's always my Barb Half orc with 8 CHR talking no matter what. And this was an intended patch???? Wtf.

I've reinstalled the game for the patch and again yesterday with no changes. Any tips? The only thing I can think of is that it's an old save, hadn't played since october but it's late act 3 and I just really want to finish this campaign.

edit: And when I mean crash, I mean the game loads up like it was the first time. All the tutorials are back and all my settings or keybindings are back to default. It just resets the game entirely.
