Unmountable Boot vol., all drives inaccessible

After a crash a few day ago, I rebooted to a cyclical BSOD, Unmountable boot volume. The 2tb ssd has 3 drives all of which are now inaccessible---more precisely, "volume does not contain a recognized file system." This excludes the three small system partitions, one FAT32, one NTFS, and MSR. They are all accessible. WinRE could not recover anything and the standard fixes fixed nothing. DiskGenius does recognize the file system of each, NTFS, and sees the data; every file I saved was without error.
It isn't clear to me why two non-boot drives, purely stored data (well, one is a 440gb partition completely empty except for whatever hidden files are put there). The only connection the three partitions have, and none of the system partitions have, is bitlocker. Could bitlocker be involved? Any suggestions would be appreciated.

I've had this computer (HP Envy 15 laptop) for less than 2 years. I can't determine right now the version of Win 11, but I'm caught up on the monthly updates, but maybe not as caught up on features updates.

Thanks

Try repairing Partition Table if the file system not recognized.

In this guide, i will describe how to fix damaged Partition Table or Master Boot Record (MBR) with a free and open source utility called TestDisk.

Thanks for the response, FreeBooter, but the partition table seems unaffected. I must correct an error in my initial post. I said that the affected partitions were the windows partition and two data partitions and that the system partition, MSR, and OEM partitions were fine. No. The OEM partition is also inaccessible and has the same "volume does not contain a recognized file system" error when I try to view its contents (except with DiskGenius, etc.)
Also, testdisk says the boot sector is bad (doesn't match the backup) on the C:, D:, and E: drives, but OK on the oem/recovery partition.

Can you post us Disk Management screenshot?

Also where do you get this not recognized file system error message, is it Windows giving you this error?

Please Run Sea Tools bootable Long generic test > take pictures > post images or share links

Windows cannot load, of course, but with cmd, in Recovery or WinPE, I get the error by attempting to switch to those drives. In Win Explorer in PE, it simply says that I have to format the drive before I can use it.

Have you tried repairing the Partition Table with TestDisk or you are just making guesses?

Are you using diskgenius boot media?

You can borrow my boot media which has diskgenius and a lot more
23v7.iso

best to extract the iso to bootable usb because the programs run off the usb stick.

I have no grounds to offer guesses. By no means is this my area of expertise. I'm reporting what the app found. I don't necessarily accept those reports, which is why I am an happy to take the advice and kind offers from you, and now Zbook and SIW2.

Thanks. The overnight part didn't happen. Within 15 seconds it gave me the hard drive/SSD HP Failure ID 927tht-b5lc7p-mfpx01-60ae03, which I can find nowhere online. If it really is a component failure, I think anyone here has a good idea what I'm about to say: Of course, the warranty expired 2 to 3 months ago.
