I have a similar problem on Stadia where the second cutscene never plays I just start on the beach. When it happens I am not able to save game it is darkened out and says a party member is in a dialog but thats when I dont even have a party yet. Finally when I pick up items like the clam or the fisherman corpse I cant loot the item and I cant walk away or do anything. I become stuck. I had to replay the transponder fight over 3 times and then it finally loaded properly with second cutscene and able to save and pick up items. Very frustrating as this was my first experience with BG3. I know EA but still frustrating...
