I lost power when attempting to load the Sandbox. Since then, I get stuck at the Sandbox loading screen. I cannot delete any of my Sandbox games as I cannot access it. I can access the campaign without issues. I tried uninstalling/reinstalling, disabling steam cloud, backing up game files and restoring. I tried to find the cloud files on my computer to delete them, but I cannot even locate the cloud folder that's mentioned in all the guides. I uninstalled and reinstalled Steam. I think the issue is that I need to clear my progress on the Sandbox, but I can't figure out how to do that. Every time I start the game after trying various things, it still shows the progress on my old Sandbox game, which I think might be corrupted. I even tried logging on a different computer and was still unable to load the Sandbox. I can't find the "local low" folder for Two Point anywhere.

Any suggestions? Is there any way to clear the Steam cloud or erase all progress on Sandbox without going into Sandbox and individually deleting games (I cannot access it so I can't do this)?

Thank you.
