I'm still able to play, load, and save the game. The issue I've been having is ever since I used Willowtree on a character, the error code/bug in the attatched screenshot appears 100/100 times. I've tried verifying game files on steam. I've tried all the regular methods of fixing it.
Hence why I'm reaching on the support of the place where I got the problem from. I'd appreciate any help to solve this problem. Thanks everyone!
Late post but from what I can look up, it seems it may be an issue with the game not being able to connect to the internet? Either that or it's something with the graphics driver.
If you're still getting this issue, you can try playing the game offline or try to update graphics driver.
