hey! i won't be of much help since i'm hopeless at technology but i've asked a few people and here's what they suggest!
"Try to press Shift + G and then switch the renderer from automatic to either one of the other. Quit and then re-enter the game. If still not working try the other renderer. After that I don't know what else to do." (i'm not really sure what this means as i use a mac but i hope you can understand it!)
"https://lemmasoft.renai.us/forums/viewforum.php?f=8… maybe check renpy-related forums and stuff? since it might be a client issue." (from a dev who's also been having people tell them that their renpy game isn't running!)
“1. Go to the game folder where the application's exe file is located.
2. Right click the exe file and click "properties". A new window will pop up.
3. There should be a box to check down below that should be saying "unblock".”
i hope this helps! and i'll update this comment if someone else has any other suggestions ^^
