Cant connect to the Crypto provider?

I have a mail that I need to reply, and I wanted to do this with more mail. But on some mails I get the message “Cant connect to the crypto provider” on android. Sending it from Thunderbird Win11 I have no problems.

I use K9 mail for a week, and it’s connected to OpenKeychain and that works for sending encrypting mail. But resending or replying, not so much.

Samsung A54 up to date
OpenKeychain 6.0.4 60400
K9 6.603
