Edit: So, I uninstalled and then deleted anything left over. I was able to re-join with out a problem.
But, i went to put all of my add ons, screenshots, and Saves back. It started happening again as soon as I put a small grouping of Add-ons, to see if it would cause it again. Low and behold it happened again.
Going to attach my Console Log from the last time it crashed. Also, it loads CDN Files, then when proceeding to Datablocks it stops and gives that/this error.
