App Store installed iMovie Crashing, everything else seems to work.

My apologies if this has been answered before, but I did search beforehand and didn't find anything.

I followed the vanilla guide in the sidebar to get Mojave working on my Dell XPS 8930 with an i5-8400, z370 motherboard, and RX-480 4GB. The kexts I'm using are: AppleALC.kext, AtherosE2200Ethernet.kext, Lilu.kext, VirtualSMC.kext, and WhateverGreen.kext. I used the config.plist from the Coffee Lake section of the vanilla install guide, and I think I tried one small edit yesterday to disable the Intel Injector, but I'm pretty sure I did it wrong. The config.plist is here.

For my work, I only need to have a simple video editor for when clients send us movies to play back during shows, but every time I try to launch iMovie, it shows up on the dock for maybe a second, then a bit later I get an "iMovie quit unexpectedly" window.

This is the "details" section of the report button: text

I'm hoping one of you has run into this. Please let me know if you need further information.

Thank you!
