Cannot Decrypt S/MIME Emails After Upgrade to 78.5.0

Greetings:

I have Thunderbird set up to use S/MIME encryption. It has worked as expected for quite some time now. However, after a recent upgrade (I believe it was 78.5.0, which I upgraded to approximately 10 days ago), I can no longer read any emails that were encrypted using my digital cert. This includes e-mails in my "Sent" folder. My certs are setup correctly underneath Account -> End-to-End Encryption -> S/MIME. They are not expired. I have "Require encryption by default" selected but left "Add my digital signature by default" unchecked.

Looking at the Error Console, I do not see anything that to me seems related to the issue -mostly Exceptions in "L10nRegistry.jsm" , "ActorManagerChild.jsm", and "Extensions.JSM".

Any advice as to how to troubleshoot or fix would be appreciated.

Thanks.

restate the certs in your account settings. Mine have dropped off several time now over the past couple of years. When I restated them they came back with a number in brackets after the personal certificate name, then I could send s/mime signed mail... I did not try and read encrypted mail at the time, I mostly sign. But I have no doubt if I could not send I would not have been able to read.
