Same here!

The game was running completely fine before updating to macOS Tahoe 26.2, but now it's unplayable.

I have a run where I am in Act 3, after
entering Baldur's Gate.

Every time I start a conversation with an NPC where I have dialogue options, the game freezes. The only solution is to quit the game through Steam.
Initially, I thought it could have been a damaged save file. I then loaded some old save files, but the problem is still there.
I even started a new campaign. I had the same problem right before
the final battle in the Nautiloid.

I somehow managed to go through, but now the same happens when I interact with the crypt.

Please Larian help us!
