The game crashes immediately because it's missing a required extension:
addons/gdmaim/gdbc/gdbc.gdextension
Can you upload a complete build with all required files (especially the GDExtension DLL)? Thanks!

That's actually not what's causing any crashes, those errors are known and occur when it works too. It's actually most likely because of an incompatibility issue with the vulkan. To fix this, you can use opengl instead, by following these steps:
Create a new text file inside the folder you extracted the game in, name it however you want, then open it and paste this:
"Deltarune Lightners Live Plus.exe" --rendering-driver opengl3
change the file extension from ".txt" to ".bat".
Now open the ".bat" file, which should run the game
Thanks, glad it works for you now!
It would be cool to be able to just load in any midi, but it really wouldn't work, a lot of the time midis would just be mostly, if not entirely above or below whatever mid point was chosen, so maps would just end up being all 1 note.
Also, normal midis are often more than just the melody, they have the backing too, so it would either use all the instruments and the map would be a complete mess, or it would have to choose 1... somehow. The game would just have to guess which one to use, which there's not really a way to do.
And even then, the maps either wouldn't have any hold notes, or would have all hold notes, both of which would be bad.
There's going to be a big update to how maps work in the animation revamp, which will let mappers control Susie and Ralsei's animations, so even if none of those problems existed, the other notes will be used soon anyway.
