Hello I am JayKhrisDee or Jay and I need help saving data and mounting my Volumegroups in Arch Linux, I am only using the archiso live boot environment in fear of losing data.

Issue 1 - Arch Linux OS Not Loading//Couldn't Access bios.
Originally this situation started with Gigabyte Aorus B550 Elite V2 Bios Booting issues (multiple reboots, and Full Shut downs needed in order to normally boot.) I left my Computer On the Base Gigabyte Splash Screen for 3/4 Hours to no Avail I Had Slow and completely empty Boot-Ups.
I had Also Left the Grub Boot loader for 2/4 Hours because it had also froze at that screen. it still didn't load into my Arch Linux OS.
Within this Grub screen i lost control of Keyboard and My Mouse so Rebooting through CTRL-ALT-DEL was no option. So manual rebooting was required.
I repeated the last two boot processes struggling in frustration looking for some kind of answer, I Then Thought it Was My Bios So I Updated it To the 12/1/2021 Q-Flash
It went through and the Rebooting the same way. Although I did have more successful results in booting, it was the select boot driver screen rather than Grub.
And Like a Can of worms this solution added another problem which is my Main reason for contacting

Issue 2 MAIN ISSUE - My Arch Linux has Unmounted My Volumegroups
After booting into my Newly Updated Bios, the Logical Volume Groups were Unmounted, and Unrecognized from the Partitions they originated Within.
Now when I initially installed my Arch Linux System I Was very new and required tutorials
I read up on the Arch Wiki but then I took detours on my setup I mainly used the
"FULL ARCH LINUX INSTALLATION GUIDE" from LearnLinuxTV
I Put my Arch install on the: "/dev/volgroup_0/lv_root"
just as he did
as well as my home partition on: "/dev/volgroup_0/lv_home"
just as he did
Everything went well for a while all working Normally until I extended the Volumegroup.
I recently got a New Hard Drive and Wanted To Expand My Volumegroups so It did go through well fully extending without error.
I used the "Logical Volumes Explained" Video by ChrisTitusTech For assistance
youtu.be/scMkYQxBtJ4
Things went well Until The Bios Situation I mentioned recently. Now I Can't Boot Into Grub Or The Arch Linux OS,
so I attempted to see the Issues through a live environment, at least to ensure I didn't lose any data.
I made sure to be very careful in the few commands I used
No serious changes have been made yet.

(Below this was unrelated Information about my USB Flash Drive)
My partitions are still located there and has some self contained data within my Drives.
I checked to see if my Volumegroups we're still there and they were as well.
I proceeded to check Using the pvscan, and lvdisplay commands; these were the results:
root@archiso ~ # pvscan
WARNING: Couldn't find device with UUID IbA08z-s50a-mEnO-OT10-eRFx-bo1H-txeWHD.
WARNING: VG volgroup0 is missing PV IbA08z-s50a-mEnO-OT10-eRFx-bo1H-txeWHD (last written to/dev/sdb1)
PV /dev/sda2 VG volgroup0 lvm2 [<930.78 GiB / 0 free]
PV [unknown] VG volgroup0 lvm2 [2.73 TiB / 0 free]
Total : 2 [<3.63 TiB] / in use: 2 [<3.64 TiB] / in no VG: 0 [0 ]
:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
Context: the unknown drive is my secondary HDD hardrive that I used to Expand the Volumegroup. I then proceeded to use the lvdisplay command, it repeated the same terms when I used pvscan
root@archiso ~ # lvdisplay
WARNING: Couldn't find device with UUID IbA08z-s50a-mEnO-OT10-eRFx-bo1H-txeWHD.

With this information I Proceeded to do research on safely remounting logical volumes without formatting. And so far most tutorials require a wipe which is not what I want to do In sake of my data, I was tempted to do a fresh install of arch Linux but I am a little weary I might lose data through that. I will do more research before I move forward on the machine.
But I do require assistance with safely recovering my Arch Install. I don't have extra hard drives or installs to attempt this in a Virtual machine so if you can provide information or Video evidence within a VM I would appreciate that. I am Willing to pay for troubles. I just really need my data saved.
Thank you
I am Usually Available to access my computer between 9pm-5am although I am able to respond most of the time.
