We're here to help, just need more info.
I'm assuming you are using Thunderbird 60.5.2. You'll need to update it to 60.5.3, which has corrected this issue for me and at least a couple of others on the Adobe forums. Just go to Thunderbirds help menu, and see if there's an update available. You'll need to restart Thunderbird.
