It is possible that uninstalling left a corrupted file that wasn’t replaced by the fresh install. You could try deleting the file mentioned in the error before verifying game files.
If that doesn’t work you could also try uninstalling again, manually deleting any files left in the MCC folder then reinstalling again.
It was erroring… BEFORE I uninstalled and reinstalled it. The error popping up, before all that is why I verified it twice, and it claimed everything was fine and nothing needed to be regrabbed.
