I think I may have found the problem. MSI Afterburner (graphics card tool) had F10 assigned to ‘screen capture’; I tried yesterday removing the assigned key and the sim no longer crashed when pressing F10.
I’ve had the sim crash previously when trying to take a snap screenshot (SHIFT+WIN+S and then drag select the area you want to screenshot), so it’s my impression the sim is unstable when it comes to certain types of screenshotting.
Anyway, issue resolved! I am happy and can now begin to use the F10 key without fear in the sim haha.
