What follows seems a little silly to me, but maybe it points to a clear
reason for someone with greater knowledge.

I've just updated two computers from org 9.4.4 to 9.5.1. Both are
running fedora 35 with emacs 27.2

One of the installations had this problem. There are minor differences
in the .emacs files between the two installations in terms of packages and the
order in which they appear in the file. I also use use-package.

seeing the above advice I revised the order of packages on the machine
with the problem so they were close to the order on the other machine -
mostly before (use-package org ...). Restarted emacs, and the problem was
still present.

I had noticed that the statement

(prefer-coding-system 'utf-8)

appeared in both .emacs files, early in one and towards the end of the
on where the (date date) was seen after M-x org-agenda

after moving (prefer-coding-system 'utf-8) to before the first use of
use-package the problem is gone

best
