SELinux is preventing /opt/google/chrome/chrome-sandbox from read, append access on the file /home/tjw344f/.xsession-errors.

*****  Plugin restorecon (98.5 confidence) suggests  *************************

If you want to fix the label. 
/home/tjw344f/.xsession-errors default label should be xdm_home_t.
Then you can run restorecon.
Do
# /sbin/restorecon -v /home/tjw344f/.xsession-errors

*****  Plugin catchall (1.48 confidence) suggests  ***************************

If you believe that chrome-sandbox should be allowed read append access on the .xsession-errors 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 chrome-sandbox /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

*****  Plugin leaks (1.48 confidence) suggests  ******************************

If you want to ignore chrome-sandbox trying to read append access the .xsession-errors file, because you believe it should not need this access.
Then you should report this as a bug.  
You can generate a local policy module to dontaudit this access.
Do
# grep /opt/google/chrome/chrome-sandbox /var/log/audit/audit.log | audit2allow -D -M mypol
# semodule -i mypol.pp
