What specifically went wrong when you tried that?:
First time to download and install Psychopy. after installation completed, I clicked “pyschopy 2024.2.4”, then a rectangular opening screen appeared in the center of the screen, similar to the welcome scene, after about 3 seconds, it just went away and nothing happened.Then I tried to start “pyschopy 2024.2.4 builder”, "pyschopy 2024.2.4 runner, " “pyschopy 2024.2.4 coder”, the same thing happened-- only welcome scene jumped out, then quickly gone. I dont know how to fix it.

Thanks for your help.

But, I deleted everything in the AppData Roaming and Local folders, uninstalled and reinstalled, failed to fix it. Frustrated…
