Apple Mail shows 'Mail Attachment' icon instead of email content

I use primarily use Apple Mail (Version 16.0 (3864.700.51.1.1)) to read my email. Frequently I just get a "Mail Attachment" icon rather than the content of the email. I know there is content, because I see it on other app's.

Any idea why this is happening?

Mac mini, macOS 26.6

I use several different computers and a cell phone to manage email. I use Thunderbird and Outlook on Windows 10 & Windows 11, evolution mail on debian and ubuntu linux, k-9 mail on an android device, and apple mail on a macbook air. I also use webmail when necessary on all of the above machines. Just this week I started getting "Mail Attachment" in about 10% of the emails I receive, and no other information. I have not seen this before. The same messages open perfectly well on all other mail clients, and in webmail. I have more trouble with apple mail than all other mail clients combined. Since this problem appears only on apple, what is wrong with apple mail?
