Problems with 5.7k video in unity on the oculus go

alrighty, so the program I am making is a simple video shell app so all it does is allow the player to pause the video and click on some pre-defined targets that give some info about the thing in the video. pretty basic right? so I am using unity and how I am playing the video is by playing it to a render texture and using that render texture as the skybox and that all works fine. so far I have been testing it with 2k footage and that runs fine but I read on this page: Encoding High-Resolution 360 and 180 Video for Oculus Quest and Oculus Go [Updated to Include h.265 Support](on the Oculus Creator blog) that you can use 5.7k @ 30fps (5760x2880) so I got new footage and the 6-minute clip was 2.8gigs added it to unity and built it out to my go and tried to run it and I don't even get to the made by unity page it just crashes.
so I guess my question is this does the problem lie with the resolution of the footage or the size of the footage or unity?

Thanks in advance.
