Hi,
my situation was like so:
I am using Thunderbird 102.6.0 under an up to date Fedora 36.
I have an email account registered into Thunderbird. I have an RSA key with a passphrase added which I use to sign an decrypt as needed. I use a master password.
That was the situation before today. No update to Thunderbird have been made since the issue, nor to the system (afaik).
I can not sign and decrypt messages anymore through Thunderbird. For instance, when I seek to send a signed email Thunderbird gives me a popup with: `Unable to send the message, because there is a problem with your personal key.`.
Signature verification still works so at least Thunderbird can access my public key.
I go to the Thunderbird `Account Settings` and under `End-To-End Encryption` I see that the selected personal key radio button is greyed out. It says that the private is not available or readable (I dont remember, the message disappeared when I selected a radio button repenting an other key in the list...).
I check the Thunderbird OpenPGP manager and see that there is indeed a key for the email address associated to the account (see the attached picture).
This key pair is valid enough so that I can manually encrypt and decrypt using the `gpg` command (using a terminal, not under Thunderbird).
Any idea why Thunderbird forgot about the private key ?
