Game will not allow me to continue Campaign

When I enter the campaign select screen and click continue campaign it shows it loading normally but then reverts me back to the screen. I have tried verifying the files, closing the game, and shutting down my computer but none have worked. Can someone please help me find a solution? Thank you. (This issue is on MCC pc)

Unfortunately there no real fix. Your progress in that mission is gone but you can reset the mission if it was a playlist you were working on.
if you resume the campaign mission/ playlist with 2+ players, it will reset it, then you can back out and resume it solo so you don’t have to reset the whole playlist. Hope this helps.
