I’m with the same problem here…already format meu pc, recent install and dont know how to fix…it’s a engine bug?
They update the page about setting the visual studio for unreal engine adding 5.1 with new specific requisites and now it’s working!!!
I followed the installation step by step, but it still doesn’t work
