I've used Nova Launcher forever. Never had a phone without it. However I've noticed some things missing since the Android 12 update. I used to get the options to remove or uninstall an icon/app when long pressing it. Now those are missing. I have the uninstall option turned on but still not showing up. The remove from homescreen "X" is completely gone from the options. Nova's customer service has always been horrible. Nonexistent. So a solution is probably not easy to come by.
