Critical Error - Sporadic checkout issues, error thrown referencing Eway SavedTokens

[studio48internet]

Hi

We're currently running Magento 2.4.3-p1 with Eway 3.1 and are having sporadic checkout issues. This affects all payment types, but the error appears to reference an issue with the extension:

Frustratingly it doesn't do this consistently - perhaps one in twenty transactions or so. The result is that the customer sees an error along the lines of the order wasn't successful, but in reality the payment was successful and appears in the quote_payment table but the above presumably breaks the sales order creation and the result is a "ghost" order.

Is this a bug with the Eway extension? Any advice appreciated.
