Payment Processor Error message :Failed to update contribution in database -- still an issue

I have also filed this issue at: https://lab.civicrm.org/extensions/stripe/-/issues/323

Not sure which is the proper queue for issues on this project.

I have a site exhibiting this behavior: https://lab.civicrm.org/extensions/stripe/-/issues/162

Rather than a payment confirmation page, the workflow cycles back to the donor page with this path: /civicrm/contribute/transact?_qf_Main_display=true&qfKey=CRMContributeControllerContribution2r--a-very-long-hash

displaying at the top this error message: Payment Processor Error message :Failed to update contribution in database

Investigating the stripe account, this transaction seems to have completed successfully.
