If you're on PC/Steam you can revert to patch 6. In steam go to your games properties -> betas and there choose the patch 6 branch. It will reinstall the "working" version of BG3.
I 'm not going to upgrade until my current PT is finished. Probably still some weeks from now, and I *hope* that by that time the bugs are fixed and the good old mods work again with the latest version. If they don't I'll probably stay on 6 forever. I don't need evil endings, but i need my mods.
