Error Code GIJU:E215:E215

I opened an old archive and it needed to be upgraded and received the following error:

Error Code GIJU:E215:E215

Any help would be appreciated.

Welcome to the Cryptomator Community :slightly_smiling_face: ,

the solution can be found in the thread Migration fails.

In short: Over time Cryptomator changed the definition how a vault is structured (called vault format). The desktop app offered/offers migrations from older version, but only to a certain older version. Yours is so old, you need older versions of Cryptomator. Just read the linked thread.
