For everyone having issues with the game crashing if you hit F4. Install Microsoft visual studio https://visualstudio.microsoft.com

After that. go into the rampage file<Rampagefiles<settings. It should prompt you or automatically open visual studio. Scroll down until you see "Keys". in the "Open Key" Set it to a different key code https://learn.microsoft.com/en-us/dotnet/api/system.windows.forms.keys?view=windowsdesktop-9.0 (this is a list of all the different keycodes on your keyboard. Replace 115 with your desired keycode and use that key to open it instead of F4. It worked for me, I hope it works for you :)
