Description of problem:
I upgraded to F35, rebooted, and this showed up.
SELinux is preventing ModemManager from 'create' accesses on the qipcrtr_socket labeled modemmanager_t.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that ModemManager should be allowed create access on qipcrtr_socket labeled modemmanager_t by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'ModemManager' --raw | audit2allow -M my-ModemManager
# semodule -X 300 -i my-ModemManager.pp
