I have had problems with Linux crashing, and I have enabled crashdump. Especially one line in the logged dmesg I found interesting:
[ 8906.236858] kernel BUG at fs/inode.c:611!

Does this mean a kernel bug, or can it be something else?

I also have a full dump, but I don't really know how to use it

Have you saved old Kernels? Can you use another instead and see if it has the same problem?

I previously tried ubuntu 20.04 (with 5.15 kernel). The problem was there. Also i tried to install my system on different ssd drive (but the same model) - same error.

I have had problems with Linux crashing, and I have enabled crashdump. Especially one line in the logged dmesg I found interesting:
[ 8906.236858] kernel BUG at fs/inode.c:611!

Does this mean a kernel bug, or can it be something else?

I also have a full dump, but I don't really know how to use it
<snip>
Also asked here:

Evidently it's a known kernel bug reported here: https://bugzilla.kernel.org/show_bug.cgi?id=215902.

It appears to be associated with the f2fs filesystem, which is used for NAND flash memory-based storage devices, such as SSD, eMMC, and SD cards.

I'm also running that same kernel on my Proxmox server and I think I may have experienced the same freezes/crashes every now and then but not sure because I never checked the tty output. I actually switched to the "5.15.107-2-pve" kernel today to see if that will make a difference.
