webgui and ssh unavaliable due to issue with LXC container *how to fix???*

very new to the forums. im pulling my hair out over this issue.

lenovo thinkcentre m92
i7 4th gen
16gb ram
256gb ssd boot drive (proxmox 4)
500gb hdd x2 (zfs pool equivalent of raid1)
lxc container running debian 11

i was tryna get nextcloud working inside of a debian 11 lxc container last weekend. also have a zfs pool. i briefly spun up nextcloud in docker for testing but shut it off. last night i went to use plex, also running on the same lxc container and noticed that neither plex nor the web gui was working (unacessable) and ssh into proxmox OS itself and the lxc container is not working. normally this means that my pc running nextcloud has crashed.

i reboot it. it boots up and is saying "overlayfs: upper filesystem missing required features"
the webgui isnt avaliable and neither is the lxc container.

lots of reboots later, and lots of reading this forum (https://forum.proxmox.com/threads/need-help-cannot-access-web-interface.123455/) i look at other issues, i stop getting the "overlayfs: upper filesystem missing required features" and i see people checking if the pveproxy service is running (it is)

tried booting into recovery mode and got this Screenshot from 2023-10-07 12-18-55.png

i run journalctl journalctl -b -eand see lots of bitching about my lxc container docker and apparmor and failed to mount therein.

so atm im stuck, it appears that i i cant access the webgui at all cause of this error, and i cant ssh into the host OS or into the lxc container and uninstall docker.

i really really dont want to have to reinstall proxmox, that would be a complete kick in the nutts.
