Sheeesh

Hey guys I don't know if this will help anyone but I was having the same issue and I was able to fix it. I play grounded on PC game pass and ran into the issue of saves not loading, endless processing circle, and then showing no saves at all or even being able to save in singleplayer and multiplayer when making a new game. I tried everything like reinstalling, repairing files, and even restarting my PC. The only thing that did something and fixed my issue was literally disconnecting and reconnecting my internet on my PC. I did it once when I was outside the game and noticed a change once I was in the game but it was still broken. So while still at the save loading screen I then disconnected and reconnected the internet again and the game completely froze and crashed so I had to close and reopen but this time everything fixed itself. I hope this helps someone and I would say just keep messing with it since it may be tied to internet.

Hey so I had this exact same problem just today and I fixed it myself somehow. I tried uninstalling, verifying and repairing game files, and even restarting my PC (I use PC game pass). None of these worked, but when I turned my internet on and off a couple times it magically fixed itself. I'm talking straight up disconnect and reconnect your internet not the online and offline for Xbox and such. Make sure to try a couple times and do it while at the save screen and outside the game. When it worked for me I did it at that save endless loading screen and the game completely froze and basically crashed so I had to close it, but when I reopened it was all working again. I hope this helps.
