I receive the following error message when attempting to login to the Keeper Password Manager extension. I have removed and re-added the extension with no change in results. I am using Firefox 101.0.1 and the latest version of the extension. Thanks for any assistance.

"A mutation operation was attempted on a database that did not allow mutations."
