Windows, It works fine if i use the executable in the folder
Did you see this?
I did not in the first place but it should've worked fine with both itch.io launcher and running directly. I've checked and I can run through Itch.io without issue. Could you ask Itch.io support if there is any issue with them?
I reinstalled it in itch and now it works fine
The issue seems to be that Itch takes super long to ask if I want to launch retroarch.exe or retroarch_angle.exe
