So I played for a few days on my pc. No issues. Played a few hour on my laptop, no issues.
Then went back to my Desktop, load screen at game start, nothing would work.
Tried the Backup restoration as per instructions, still did not work.
What did work, was deleting the additional Character that I created on my laptop, leaving the original one I created on my Desktop. ( I did this by going into the Charaters Folder, and deleting the folder)
Game loaded normally, and I was able log back into the game (yes lost some progress, but at least not a whole new start)
I also disabled Steam Cloud Saves, I guess I cannot play on my Laptop for now…
I hope this helps!
