Advanced Threat Defense Blocked Mozilla Thunderbird. Any Suggestion?

Hi everyone, I had a exploit alert on my pc this morning. Bitdefender Advanced Threat Defense blocked Mozilla Thunderbird: this is very good, but now I cannot open it any more. What can I do? There is no message explaining how to resolve the problem. I did a quick scan but nothing changes, the message says there is no threats on the computer.

This is the screenshot:

Thanks! 😊
