I have a self-hosted instance in which I can’t currently update any of the items in the vault. The error showed is `Encryption key type mismatch AesCbc256_B64 Payload type AesCbc256_HmacSha256_B64 Decrypt context: no context` and then my session is closed anytime I want to update or delete an Item or collection.
I have a 1.34.3 version but I updated it 3 months ago from the 1.32.7. The Diagnostics page shows

Then, is there something I can do to solve the bug or do I need to start fresh with a new instance?
