The "sm64coopdx.exe" doesn't open!

[Ordinari2010]

Hello, I'm new here, and I need help solving an issue I'm facing.

Basically, I tried to update the Coop Deluxe files to version 1.1.1, but something went wrong. When I try to open “sm64coopdx.exe”, a window flashes really quickly before disappearing. It happens so fast that I couldn't capture a screenshot, but I did notice a black screen, and the root folder path of the game was displayed in the window.

I've tried everything, including running the program in administrator mode. I even downloaded both the SM64 Coop DX OpenGL and DirectX versions, but neither works.

Does anyone have an idea what might be causing this?

(Sorry if my explanation is unclear, I'm using a translator.)

Open the game through the terminal with the --console launch param and send the output here

Does your windows username have any non-alphanumeric characters in it? If so, you will need to do this

Thank you so much! I followed a few steps and it worked!!!
(by the way yes, it was non-alphanumeric characters in username.)
