SupportAssist and Win 11 upgrade

I have a Dell Inspiron 3583 laptop. I just upgraded from Windows 10 to Windows 11. I then ran SupportAssist (I think it's version 3.11.4), which was already installed and working correctly with Windows 10 on my computer. It seemed to work fine with Windows 11, but it deleted a very large number of Windows registry files. It didn't find any updates. I'm now wondering if it thinks I still have Windows 10 and it deleted the Windows 11 registry files. Was I supposed to reinstall SupportAssist after upgrading to Windows 11? Is there a different version of SupportAssist for Windows 11? Or does SupportAssist recognize automatically that I now have Windows 11?
