ok, I checked
when changing the resume parameter in cmdline from uuid swap partition to uuid
luks partition with swap partition, the system boots correctly
but if the same change is made in fstab, then after booting the system swap
will be unused. which in my opinion is logical, because this uuid does not
point to swap but to luks encrypted partition.

I returned the uuid swap partition to swap, and left uuid luks with swap in
cmdline, so the system booted correctly and swap worked.
however, this did not lead to hibernation working:

sorry, I'll take this into account in the future
