Integrity check failed after import data

[SquallZ20]

I recently installed the latest version of syspass and did an export of the accounts from the old version the 2.1 and imported the accounts into the new one. The accounts were created but quado I try to see the passwords it gives me an integrity check failed error. I tried to do the import with the correct master password from the old syspass but it gets stuck loading and when it finishes loading it logged out and didn't import anything. How can I solve it?
