SELinux is preventing /usr/libexec/gdm-session-worker from 'write' accesses on the fifo_file /run/systemd/sessions/1.ref.

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

If you believe that gdm-session-worker should be allowed write access on the 1.ref fifo_file 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:
# grep gdm-session-wor /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
