I have been having a problem for several years that may be the same thing. My mail is in IMAP via dovecot. Other than the following I have zero problems with it. I read mail with gnus (emacs built w/o x11 running in tmux in an xterm, on NetBSD, currently 28.2 and thus the included gnus), with about 300 folders, about half of which have server-side filing of list mail. I also use K-9 Mail on Android (INBOX and maybe 3 more mailboxes, more or less, ignoring the folders for lists and storage). Occasionally I use thunderbird for INBOX, to read something that should have been plain text and isn't :-) but this issue has happened with no tbird running at all. Often, I get a message on my phone that I just leave (marked read) to deal with later. Sometimes, maybe 1 in 50, I can't find it in gnus, and on looking harder find that it is just not showing up there. Yet K-9 sees it as present and looking in ~/IMAP/cur shows it was well. Whenever this has happened and I look with Thunderbird, it sees it fine also. I have found that if I move the message to another folder (I have TMP for this very purpose) and then back to INBOX, it can then be found in gnus. So something about the message as it sits in the folder was triggering gnus to miss it, while the very same message refiled does not trigger this. I have not been able to determine any pattern of which messages get this disappearing treatment. It's not really the message, since moving and back fixes it. Early on, I sort of suspected dovecot, but other people don't have trouble with dovecot, and I have had zero flakiness other than this specific issue. I have not perceived "gnus says there are new messages but there aren't". I am not at all sure I would have noticed, especially if gnus said 6 and there were 5. In your case, if you do "100" in group, do you see the missing message? If not, you should be able to turn on some kind of debugging to figure out what's going on, but I am unclear on the details.
