Help needed

Hi guys im after some help as my Proxmox instance isn't working right.
I've had it running great for about 6 months now on a mini pc with 3 LXCs and 1 VM.
Everything seemed fine last night but this morning my Home Assistant wasn't working which is the VM so i logged into Proxmox ok and LXCs, VM and storage were all grey and saying status unknown.
My unifi LXC seemed to be still working though as i could load up the web UI.
I copied the log info while i was on and couldn't see any errors reported but I'm sure what I'm looking for tbh..
So i thought i would turn off the pc and restart and hopefully it would boot back up but i've tried it a few times and now even proxmox doesn't seem to be loading, I say it's not loading but filezilla is still connecting to it with sftp and i can view the files.
I have a usb hard drive attached to it and it's been doing weekly backups of my Home assistant and Unifi but i really can't remember what the mnt addresses are or how i would restore the backups.
How can i go about getting this back up and running ? i'm not great with the CLI commands as i was just following youtube but try my best.
Any help appreciated.
Thanks
EDIT
after some googling i ran

journalctl -f

and the 2 errors that kept coming through were.

Dec 17 12:33:54 pve pveproxy[3663]: /etc/pve/local/pve-ssl.key: failed to load local private key (key_file or key) at /usr/share/perl5/PVE/APIServer/AnyEvent.pm line 1998.

Hi Steveuk,
it seems that your filesystem was mounted read only, wich could have multiple reasons, hardware failure being one of the most probable.
To find out why your hard drive was mounted read only, you can run dmesg. This will produce a lot of output, but you could filter it for the word mounted for example, like this: dmesg | grep "mounted".

Hi thanks for the reply.
It took a while for this to be approved so I've not got that install anymore as I decided to format and try again.
But I'm stuck in a bit of a loop now I downloaded the latest ISO image of proxmox and it booted fine and I entered my details and it said it's installed and to to.the IP address but when the system rebooted it kept going to fresh install page!
So I flashed my older version of proxmox (7.4) onto the SSD drive but now I see a ACPI bios error message appear at the top and then it pops up with no hard disk found.
All my googling is suggesting bios settings about raid and ahci but I haven't changed the settings since it was working and I can't find and settings in my HP 250 G6 bios for them.
I've tried 3 different SSD drives by the way.
Any ideas
Thanks

First off, what happened with the most recent install, if you unplugged your installation media and tried to boot? Maybe it was just a matter of wrong boot priorities?
Since it already had worked previously, I would suggest resetting your bios and disabling secure boot again. Generally, it would be a good idea to check if any bios updates are available, as they sometimes improve linux compatibility.

I didn't try booting without it so not sure.
There is a update for the bios which I've downloaded but I'm struggling to create a bootable flash drive like the instructions tell me to.
It says the bios .exe file will pop up with the it option to create a bootable drive but it never dies it just extracts the files.
I'll reset the bios to default through like you say see if that helps.
Thing is though it is actually boring off the drive to the proxmox menu it's only when I click to install I get the error.
