Had the same issue during the beta and now into launch. As a person in IT, I've put in nearly 20 hours into troubleshooting, trying to get it to work, following every article, tutorial, etc. I could find. I've uninstalled everything (even within GP), reinstalled, cleaned uninstalled GPU drivers, updated bios and Windows, set Windows Defender exceptions, everything... and the only thing that has worked so far is creating a local Windows user and launching from that account. Incredibly furiating. I've seen someone else use the Windows Media Creation Tool to "repair" their Windows image, and it worked for them, but not for me. I've tried basically every option, and the last one is factory resetting my PC.
I would PAY if anyone had a proper solution to this. I have seen so many people having the same issue. This needs to be recognized by the devs! (pls I'm begging lol)
