Unable to delete admin account in the console

Hey, I have a problem deleting one of our local admin users on InsightVM console. On the first try of deleting the user, the system recommended to transfer all existing reports to another user, and that is what I did. After that, there was no notification or so whether this was successfully done or not. Now when I try to delete the user, it just keeps saying “deleting” in the banner but nothing happens.

Any tips? Is there a way to force delete user from cmd?
