:Not sure what the issue is, I'm new to fedora... Gnome shell crashed, I hit ctrl + alt + backspace, logged in and went to restart google chrome, then received this error. It looks like it is linked to google chrome trying to load recovery data.

:SELinux is preventing /opt/google/chrome/chrome from using the 'ptrace' accesses on a process.
:
:*****  Plugin catchall_boolean (89.3 confidence) suggests  *******************
:
:If you want to allow sysadm to debug or ptrace all processes.
:Then you must tell SELinux about this by enabling the 'deny_ptrace'boolean.
:Do
:setsebool -P deny_ptrace 0
:
:*****  Plugin catchall (11.6 confidence) suggests  ***************************
:
:If you believe that chrome should be allowed ptrace access on processes labeled unconfined_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:
:# grep WorkerPool/1323 /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp
