Doc Text:
Permissions for insights-client added to the SELinux policy Cause: The insights-client service requires permissions which were not in the previous selinux-policy versions. Consequence: As a consequence, some components of insights-client did not work correctly and reported access vector cache (AVC) error messages. Fix: This update adds new permissions to the SELinux policy. Result: As a result, insights-client runs correctly without reporting AVC errors. Resolves: 2190178 2207894 2214581 2224737

Description AllenF 2023-07-22 15:21:00 UTC 
Description of problem:

SELinux is preventing /usr/bin/python3.9 from 'unlink' accesses on the file /insights-redhatWS.local-20230721232748.tar.gz.

*****  Plugin restorecon (99.5 confidence) suggests   ************************

If you want to fix the label. 
/insights-redhatWS.local-20230721232748.tar.gz default label should be etc_runtime_t.
Then you can run restorecon. The access attempt may have been stopped due to insufficient permissions to access a parent directory in which case try to change the following command accordingly.
Do
# /sbin/restorecon -v /insights-redhatWS.local-20230721232748.tar.gz

*****  Plugin catchall (1.49 confidence) suggests   **************************

If you believe that python3.9 should be allowed unlink access on the insights-redhatWS.local-20230721232748.tar.gz 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:
# ausearch -c 'platform-python' --raw | audit2allow -M my-platformpython
# semodule -X 300 -i my-platformpython.pp
