Custom Modpack not launching correctly

[PyroSweets]

My friends and I made a custom modpack with all our favorite mods in 1.12.2. I was having some issues with the modpack.jar that made it run vanilla and I fixed it, but now the modpack doesn't even show a java client or loading screen before crashing. I posted a day or two ago on reddit and was told to delete some iffy modpacks, but that only makes it run vanilla again. Any ideas why this is happening?
