Error decrypting BLOB

Hi,

I ran a full maintenance but hitting this error right at the end. How do I fix it? The repo is on BTRFS disk running on Debian. It is a very large repo, 1.8T.

Finished full maintenance.

error deleting unreferenced blobs: 

unable to load active sessions: error decrypting session: 

sb10b16242ecf8b9798c0953fc99c3db5-s0cd3e7263d9d288c131: error decrypting BLOB 

sb10b16242ecf8b9798c0953fc99c3db5-s0cd3e7263d9d288c131: ciphertext too short: 0

Well… Kopia can’t read the blob - hence the ciphertext length being 0. First thing I’d do is to check the storage for errors. Then, I’d try to copy the blob somewhere, just to see, if that blob file can be read.
