Attachment: enigdbug1.txt

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:87.0) Gecko/20100101 Firefox/87.0

Steps to reproduce:

I use Thunderbird 78.7.1 (64 bit) under Ubuntu 20.10. I recently imported the Enigmail settings and keys without difficulty. The keys I use are valid, and they have been trusted, accepted and certified as explained in the tutorial here : https://wiki.mozilla.org/Thunderbird:OpenPGP:Migration-From-Enigmail.
I am trying to send encrypted emails to my usual contacts...

Actual results:

I am no longer able to send encrypted emails. I get the error:
mimeEncrypt.js: caught exception: Error
Message: 'failure in finishCryptoEncapsulation
Also, the attached enigbug.txt log file mentions mime, Enigmail, and Chrome, which I do not use...
In the attached file, I have changed my email address to [e-mail] and my key to 0x1A1A1A1A1A1A1A1Akey. Recipient is [e-mail] with key Ox2B2B2B2B2B2B2B2B

Expected results:

The email I want to send should simply go the the selected recipients.
