The custom campaigns I'm subscribed to are: The original UnderLord - DK1 Remake, Dungeon Keeper 2 - tribute, True Mystical Journey., Rise of Overseers. Dark Crusade Enhanced Edition., and Inhibitors Must Fall. I'm also subscribed to 431 maps, so I will not be listing each one of those individually as that's not practical.
I have deleted the map heroes of the past, and it did not resolve it. I also tried removing all workshop maps, then redownloading them. That also did not work. I do not own any of my own custom maps.
I left the game running for 15mins after it froze from clicking on the custom campaign, and it popped up that the program stopped running.
I would like to make note that when I try to verify the integrity of the game files, it says, "1 file failed to validate and will be reacquired." But I'm pretty sure it doesn't reacquire it because if I verify the files again it says the same thing.
As for my other PC build and output log, I can not acquire the output log at this time for my girlfriend has it. But the specs are as follows:
CPU: i7 9700K
RAM: 8gb DDR4
