Description of problem:
SELinux is preventing gnome-session-b from 'watch' accesses on the directory /run/systemd/sessions.

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

If you believe that gnome-session-b should be allowed watch access on the sessions directory 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 'gnome-session-b' --raw | audit2allow -M my-gnomesessionb
# semodule -X 300 -i my-gnomesessionb.pp
