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
