# CredentialSession.ErrorCode.acquiredResourceRelinquished

The system relinquished an underlying shared resource, preventing the operation from completing.

```
case acquiredResourceRelinquished
```

## Discussion

When the system throws this error, it also reverts the session state to [`CredentialSession.State.management`](/documentation/SecureElementCredential/CredentialSession/State-swift.enum/management).

You can attempt your operation again after receiving this error.
