TWRP Recovery: How to Create a Nandroid Backup

Question

Hello there, I had been on the save side for two years, with my TWRP, making a backup after every change on the 12+, and now I had to recover it...
TWRP 3.3.1.0 on 1.68.401.6 runs a restore without errors, but the restart ends in a bootloop.
So I flashed 1.53.401.5, tried to fastboot boot twrp.3.2.3.3, and restored my backup -> bootloop. I flashed 1.53.401.5 again, made a backup of that fresh system with booted TWRP, and tested the restore, which results in the same bootloop.
I must say that the twrp versions are correct for the used SW versions. The decryption process is complete.
Where is my brain's blind spot?
