Loading Bar Stuck on Almost Full to Full for 8+ Hours Upon Login (SEND HELP)
I recently downloaded a video software that froze my MacBook Pro (its older 2012/13) so I force restarted it manually, and it hasn't been able to login since, as its been stuck on the login loading bar on full.
Initially it just kept rebooting with the error message 'your computer restarted because of a problem (etc; Japanese)' but now has just been hanging there for multiple hours.
I've tried repairing the disk in disk utility multiple times, at which it says everything is okay, but made a possibly big error when before trying anything else stumbled upon an article that recommended to decrypt the disk (horrible idea), and it's been stuck on 0.0% (paused) regardless of power, and I've attempted reconnecting the battery and it didn't help it at all.
So far I've deleted the program from terminal (rm -r) and the app save states, and it hasn't helped, and I recently have been trying to do some stuff in single user mode, but there's a lot I can't do because of the decryption process and my lack of knowledge (and I don't want to permanently damage anything due to that lol)
I'm sure reinstalling Catalina would fix the issue, but that's not possible due the decryption.
I also attempted to back up the ~300gb (1TB) [HD - Data] to an SSD, and it force restarts every time after a short while into the imaging process.
I just signed up here as a last resort, if anyone could help me out, I'd really appreciate it.
I'd rather not pull the folders and reformat the disk if there is a more viable solution.
Many thanks for your consideration and knowledge and help.
