When I upgraded to Thunderbird version 91, I can no longer receive encrypted e-mails. The error message says that the e-mail does not contain a digital signature. However, when I view the e-mail using Outlook it clearly does have a valid digital signature. I tried sending a signed and encrypted e-mail to myself and others, and everyone else received it but I cannot read it because it says it does not have a digital signature. It worked fine before this recent upgrade.

Encrypted how? are you using the PGP implementation or s.mime the more mainstream of the two, but apparently the poor sheep these days.
