I just got this game a week or so ago, and have been having this problem since I downloaded it. Every time I go to load up any of the workshop content I have, I get this error and the models affected show up as little orbs that I cannot interact with. Sometimes only a few things error, and other times almost everything does. My friends have the same workshop content and have no issues whatsoever. I have already done the following:

-Deleted ALL files associated with the game and workshop content for this and reinstalled
-Checked all anti-virus and firewall settings
-Disabled mod threading
-Disabled mod caching
-Verified game data
-Unsubscribed and resubscribed to all workshop content
-Checked that all drivers were up to date

I have been searching for someone with a similar problem, but have not come across any threads for it. Any help is appreciated.
