I got done making a short little project in Unreal 5.6.1 and I went to go package my game for windows and it kept giving me an Error saying “Unknown Cook Failure” which is also an issue I only started having when I realised I had the wrong level set as the default one so I switched it to the one I wanted. In the crash it mentions something about a GravityGroupIndex not being less than 8, but I don’t have much experience with Unreal Engine and it’s driving me crazy trying to figure out what I’m supposed to do with that info, so I’m hoping someone can explain how to ensure that stays at 7 or lower. If I didn’t give enough info for help then let me know, I’m still very new to all of this.
(Here’s where the Errors started until the crash)
