As you can see from smartctl there are no serious errors, and I repeat: four days ago I didn’t seen the message error in journalctl.

Have you run BIOS diagnostics of the drives? They might shed light on the drives.

Yes: all stages are marked as PASSED.

You’re above my paygrade, sorry.

Don’t you worry: thank you however for your attempt :+1:
