Thunderbird 128.2.2 esr - PDF attachments are sometime damaged and cannot be open.
PDF attachments to emails are sometimes corrupt. They are not displayed when the email is opened (only a blue line is shown); after they are saved they cannot be opened (Adobe and also EDGE give a message that the file is damaged). The same attachments can be opened and saved correctly using the free Outlook application from Windows. I noticed the problem this month. The installed version of Thunderbird is Thunderbird 128.2.2 esr - but the problem also existed with version 128.2.1.

Perhaps your antivirus program is corrupting the download. It has happened frequently in the past.
I do not think the problem can be originated from the antivirus program (in my case Defender) . The same email once downloaded from the Outlook App running on the same PC does not have the problem, the PDF attachment always opens correctly. It cannot even be the internet connection, as the problem never comes up in Outlook. So the issue must be in Thunderbird, either something went wrong in the Account settings (@outlook.com) or in the recent updates. I have been using Thunderbird for about ten years and this problem has only occurred in the last month.
