I had a backup of BO7 Warzone Season 1, and I had not played for days. I had backed up my game by keeping a copy of Steamapps > common folder. I reinstalled steam and pasted my game back, and it did not detect at first. Later on,I did some settings, and the game got detected. I further updated the game to 70gb more. After all validation of game integrity, I ran the game, but this error pops out everytime. I don't know what the issue is. I have verified the integrity many times from steam but everytime this pops up. This never used to pop out back in the past. How do I fix this? Please share the solution?
