Yes I know enough about Single User Mode to navigate, view, and remove files (if the system doesn't block me out with a read-only issue). But if you know how to use Single User Mode (and the MacBook Air will let you do that), try it from that angle. Safe mode won't work as it won't reach the desktop it just gets stuck at 90% progress bar. If you mean holding down the shift key on startup, then I can confirm I was not in safe mode. If you are in Safe Mode, I'm kind of surprised you can't remove this file. I'm not sure how old the Mac is but it certainly appeared to go into Single user mode as it entered it almost immediately on startup after holding down Command-S and it didn't load any macOS GUI.

I cannot change the setting because the computer has no administrator account.
