We had this issue recently. Raising a request with Qlik . There was no solution from the team.
However, this happens due to the access issue. The access is moving to the client device/account in the HUB. Possible to have someone edit a security role? Yes. There was nothing set up in our site. The solution for this was to repair the Qliksense installation. For us the service dispatcher was corrupted. The repair fixed it.
You will notice there is some issue with the Qliksense bundled VIZ. You will have to import them again.
