Same here. I almost tried everything to get the game started - but nothing works.
I never installed mods - so this cannot be the problem.
Two days ago - I downloaded the big #7 Patch at the same time - I could play BG3 without any problems. But after it finished downloading and I started the game it crashes at 58%.
I uninstalled BG3 and downloaded it- does not work. I changed from DirectX11 to Vulcan- does not work.
I deleted the LevelCache - does not work. Starting without the launcher - does not work.
I updated my graphic card driver - does not work. There was no change in my hardware. So...I am really confused and hope that someone can help us.
UPDATE:
I found a solution and the game finally starts again. But it has a price. So...to get it fixed delete the Baldurs Gate 3 folder in %LocalAppData%\Larian Studios (just copy that into your location bar in the Explorer and hit Enter). There you will see two folders. One of them is the Baldurs Gate 3 folder. Delete it. But attention - there are all the savegames in it. So...make a copy of them!!! I didn´t try to copy them back and will now start a complete new run. But it´s ok for me because all my characters have been low level.
I found the solution here:
