So this issue started yesterday (8/7/2018). Was doing Rathalos Extreme, no problems at all until I went to leave the instance. Upon leaving, the game hung and force closed itself, no error message, no nothing. Upon trying to relog on that character, it gets as far as the loading screen and does the same thing and hangs for a second and closes with no error message.
To confirm it was just that character, I logged into my other characters on the same server and loaded in just fine.
I left it overnight and tried again today, and was able to load in just fine and run duties without issue. And then out of nowhere, the game does it again and once again I'm locked out of that character.
Only information I've been able to gain is from the Windows Event Viewer:

This error has not shown up at all since before yesterday.
Things I've tried to fix it:
-Switching from DX11 to DX9
-Compatibility mode set to Windows 7 (gave a DX11 error doing this)
-Logging into other characters
-Reset my PC
