I sent a bug report to Larian, I highly encourage everyone in this thread to do the same and to include your save file. This will only increase the chance of Larian noticing how gamebreaking the bug is.
This is where to find your save files (Windows): C:\Users\[username]\AppData\Local\Larian Studios\Baldur's Gate 3\PlayerProfiles\Public\Savegames\Story
Unfortunately I'm playing over GeForce Now, so I can't attach the save file ...
But for all those who are suffering from this bug, please report it so we can get it patched ASAP.
