00000000-0000-0000-0000-000000000000 is my error code and message says that some game files are damaged so tried using the option scan and repair but it said that no repairs are required which is bizzare because when i tried launching afterwards the some pop up occured, I also tried deleting game and downloading it again but to no succes.
Problem was solved by erasing one drive copy of the game files.
Backup services can cause sync issues with game data and lead to either outdated data being constantly backed up and resynced or preventing needed access for the updater to make changes as needed to the game files/settings.
We recommend going into Onedrive settings and where you manage which folders get synced, excluding game folders and in the case of this game, the Starcraft II folder under Documents. That should prevent this from happening again. /salute
