Welcome to the Cryptomator Community :slightly_smiling_face:

Your masterkey file is damaged. Restore it from a backup.

The backup is stored inside the locked vault directory. It is named “masterkey.cryptomator.XXXXXXXX.bkup”. If there are several backups, pick the most recent one. To restore:

  1. Make a copy of the current masterkey.cryptomator file
  2. Select the most recent backup file
  3. Rename the backup file to “masterkey.cryptomator” and overwrite the existing masterkey file
  4. Unlock the vault

If step 4 is successful, you can delete the copy you made in step one.

I haven’t got any of those files in any folder, I think Dropbox had done a number on me
