QuickView OS version 7.0.1.13612 Compatible with Windows 11 issues?

Has anyone had any issues Windows 11 and QuickViews? We have one individual only that cannot seem to run QVs, or if he can, it takes several minutes to do so. Any ideas what it could be that is causing this? We are on an old version of OS. We changed some preferences in the QV and that helped. We have had IT look at his setup and they found nothing out of the ordinary. We are at a total loss as to why one individual is having problems out of 50 + users. Any ideas will help. Thanks
