Plex LXC install error, and total crash of Proxmox itself

[bobloadmire]

I understand that this is probably a proxmox issue but it only happens when I install Plex.

also just earlier today I accidently rand the command "groupadd -g 10000 lxc_shares" in the main proxmox shell. Is that related? I don't know how to undo that.

I can't even ssh in, its hard bricked until reboot.
