I had a look at the test failures locally; this seems to be caused by updates on the macOS CI runners - which has been waived on the main branch via #135202 / 88e15b781506949c56936b8642774125772fdeb2. I guess we could backport that commit as well? We'd probably need to do that anyway if we want to have working macOS CI on the release branch - so that could be a separate individual backport that is done first.
