Hi Robert, if you are sure yiu have the right passphrase, this may be a defective SSD. Especially cheaper SSDs can develop bit-errors. Since most software and files continue to run and open even with that, it can take a while for that to get be noticed. With SSDs, there is the additional problem that it uses very large sectors internally, and hence even if you did not write the LUKS header, it can get changed on another write. The way these bit=errors happen is then that the SSD-internal sector gets loaded into memory, modified and written back. While protected by checksums and ECC in the FLASH chips, protection is often missing on the bus and in SSD-internal RAM and that is where the corruption happens. Due to the anti-forensic properties of the LUKS header, should this has happened, the only way out is a backup. Before you give up, make sure you have the right passphrase.
