Hi @Guenter_Mathis,
There are two separate problems here, and both are on our side.
The “Please review manually” errors come from a temporary Auto-review outage that is affecting many users right now. Your deletes weren’t judged risky; the check itself is failing. The team is working on it, so please check back later.
Reset fails for a different reason. The files saved from your computer are larger than a fresh computer can hold, so Reset stops before it replaces anything. This is a known issue the team is aware of, and I’ve added your report to it. Pressing Reset again won’t get past it.
Since you’ve already downloaded your backups, we can try wiping the computer’s data so it starts clean. That deletes everything on it, so please confirm here that you’re OK with that. If you’d rather keep the files, your bot can delete the stage folders once Auto-review is back, though that alone may not free enough space for Reset to work.
