hi i tried to install ue5 and kept crashing on load due to python 3.9, i tracked the info down to me being on windows7 and python version they built was a windows 10 thing… i.e i needed a special python installation where 3.9 was installable. but i never pursued the carnage… in short… UE5 == windows 10 support , win7 not so much anymore…
