I can not confirm this :/ When I switch my failing ZIP backup over to TAR it still fails with the following output:

tar: certbot-renew.log: Cannot stat: No such file or directory
tar: composer-self-update.log: Cannot stat: No such file or directory
tar: <something>-2024-08-06-025121.zip: Cannot stat: No such file or directory

tar: scheduled-180170.log: Cannot stat: No such file or directory
tar: scheduled-180382.log: Cannot stat: No such file or directory
tar: Exiting with failure status due to previous errors

It does not matter whether I switch deleting failed backups on or off, it always fails with the same message.
