Game suddenly stops loading saves

[abi]

Yesterday everything was OK, however today all of my saves are not loading and stuck on loading screen.
I have a pretty lot of saves (usually 2 per location) and even oldies are broken as well, except the intro ones.
Log file is rapidly filling with this particular exception

I've checked game files (I use GOG version). How game managed to break even old saves ?! There were no updates today.

I've unpacked random save and found no a8be16fc11da44bd998c607ed4d39bbe sequence inside.

Looks like full reinstall helped. Not sure whats happened though.

I got a problem similar to abi's. My game remains stuck at the introductory page with the Pathfinder Kingmaker shield. The page in which you can load a previous save, start a new game and so on never appears. I uninstalled and reinstalled the game but nothing changed
