Camera stuck in a death spin

Never had an issue like this one. Not sure how to get out of this. Would not recommend using a hotkey to walk around (default is control) as that’s how this happened. Cannot interact with the software at all. just a heads up for others. (can’t upload video; it’s too large)

Also wtf is even the point of backups? they don’t seem to save as frequently as they should & seem pointless. They’ve never saved anything useful & even though I have the autosave set for every half hour, they only backup every couple of hours, which does nothing for me
