[FONT=Helvetica Neue]When I try to open a C++ project I meet this error message. I use Windows 10, and I tried reinstalling both Unreal 4.25 and VS, the error persists. It asks me to continue with Visual Studio 2019 also, here is the error message:

EDIT:
THE PROBLEM HAS BEEN SOLVED: The problem was non-english characters on my user/home directory name. I solved this by changing my name in user/home directory. I opened a new user account on my computer with a name without non-english characters, and deleted the old one. I can now open projects of C++ cuz the programm can read my user/home directory name.
