Sorry about my very late reply 馃槄, I haven鈥檛 been logged in into Itch.io for a while, so I didn鈥檛 see your message.
If you still have the issue, and want to use Rem鈥檚 Studio, I recommend starting the engine from a terminal/console window:
there, you can see the logs, and there will probably be some kind of error message.
You can post that here, and ideally your OS version and hardware, so I can get a clue about what鈥檚 causing the issue.
(e.g. Intel iGPUs don鈥檛 support all OpenGL things, so I have to work around that; but personally, I don鈥檛 have an Intel iGPU for testing)
