Description of problem:
started a session
SELinux is preventing gnome-shell from 'watch' accesses on the directory /var/lib/flatpak.

*****  Plugin catchall_labels (83.8 confidence) suggests   *******************

If you want to allow gnome-shell to have watch access on the flatpak directory
Then you need to change the label on /var/lib/flatpak
Do
# semanage fcontext -a -t FILE_TYPE '/var/lib/flatpak'
where FILE_TYPE is one of the following: abrt_var_cache_t, auth_cache_t, auth_home_t, cache_home_t, cgroup_t, config_home_t, data_home_t, dbus_home_t, etc_t, faillog_t, fonts_cache_t, gconf_home_t, gkeyringd_gnome_home_t, gkeyringd_tmp_t, gnome_home_t, gstreamer_home_t, icc_data_home_t, locale_t, mozilla_plugin_tmp_t, mozilla_plugin_tmpfs_t, pam_var_run_t, user_tmp_t, usr_t, var_auth_t, xdm_home_t, xdm_log_t, xdm_spool_t, xdm_tmpfs_t, xdm_var_lib_t, xdm_var_run_t, xkb_var_lib_t, xserver_log_t.
Then execute:
restorecon -v '/var/lib/flatpak'


*****  Plugin catchall (17.1 confidence) suggests   **************************

If you believe that gnome-shell should be allowed watch access on the flatpak 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-shell' --raw | audit2allow -M my-gnomeshell
# semodule -X 300 -i my-gnomeshell.pp
