If you look up this error, you'll see that it comes up a fair amount with Unity titles: https://www.google.com/search?q=%22Fall ... library%22
It causes crashes AND in several instances, the exact symptom you reported in another thread:
Have you migrated Windows from another disk drive lately, or migrated the install from another PC? What about Steam, did you migrate that lately or change anything in regards to your Library location?
Posting logs is great, but in your post history I do not see confirmation that you've done any troubleshooting steps. Based on the info above I have to conclude that, as of now, this is not an issue with the game. Or at least, it's not an issue with the game that we caused directly. Now that we're linked to Steam completely (we weren't before) that opens us up to a lot of systems interacting that were not before. I have put up several links to troubleshooting steps that have helped other users, so I am going to need you to actually step through those and report back with your findings. Here is the most important of those links again: https://steamcommunity.com/app/611790/d ... 789/?ctp=2
In addition to the steps linked above, one of the fixes I am seeing related to that error message is reinstalling Steam. You can do that by following these instructions, making sure especially to copy out your Steam Apps to a separate folder prior to fully uninstalling Steam: https://support.steampowered.com/kb_art ... &l=english
