Can you check if you have anything inside Soulash\logs\errors.log file? This sort of thing sometimes happened due to a missing asset file. Could you try downloading the game again through the itch app https://itch.io/app?
Attempting to launch it through the app doesn't even open a window or start a program and trying to run it from the app's install location also brings up the empty console. In no case is an error log produced.
