Tour de Zwift 2023 Stage 7 Ride

Twice now I have started Tour de Zwift 2023 | Stage 7 | Ride and both times have had strange graphic problems, lines and various shapes eventually kicking me out and back to a Windows 11 screen desktop. Have uninstalled and reinstalled Zwift and also Windows but to no avail. Ridden in other worlds today and it’s fine but still does not like Makuri. Is this a common problem?
