Cryptsetup luks still broken

some time ago, I was trying openWRT 22.x and I was wondering that I cant use luks encryption. The solution was, to use openWRT 21.x ... There works luks encryption fine.
Now, I testing openWRT-snapshot and luks encryption is still broken. Formating with cryptsetup works fine and then formating the encrypted partition with ext4, works fine, too. No, problems with mounting it.
But when I copy/move/add/delete some files I get a lots of errors from dmesg. It does not matter, which filesystem I use. Every time I get errors. Do I use an ext4 partition without encryption, there are no errros, too.
I will add some screenshots. Can anybody help?
