I have some issue with saving. I can save, but then I'm locked in the screen with the saves and can only close the game completely.
Edit:
This fix
Next, try browsing to the 'C:\Users\<UserName>\AppData\Local\Larian Studios' folder and rename the 'Baldur's Gate 3' subfolder. The easiest way to get there would be to copy the line below into the location bar in Explorer and hit Enter.
%LocalAppData%\Larian Studios
This folder contains the saved games, configuration files and a level cache folder. Deleting or renaming it will get the game to recreate it on startup; playing the game from a different Windows user account would effectively do the same thing. With Steam/Galaxy running and cloud support enabled, the client would just download the cloud copy of your existing profile.
Next, extract the replacement folder from this download into your '..\Local\Larian Studios' folder, start the game and see if you can make a manual save successfully. If so, exit and copy a couple saves from the renamed folder into the newly created profile's ..\Savegames\Story folder. If that continues to let you start the game, load the saves and re-save, move the rest of the saves over.
worked for me.
