Text content of an incoming email not visible
I received an autoreplied email from my colleague. I can see the sender/subject but when I double click (open) the email, as if there were no text inside. Then I open the same email in Outlook, there is a text content. My other emails in Thunderbird are working as normal (HTML format is visible). It just happened today and only just that one email.
Window 10 Pro... Ver: 10.0.19045 Thunderbird: 128.3.3esr (64-bit) Just updated and re-checked.
Thanks.
