Minecraft crashes when I load it with my mod.

Same

I have the same problem, and sadly no answer :( I would appreciate it too!

One of the most commonly successful answers to this is to make sure there are no other mods in your minecraft mods folder, for example, if your mod is made for 1.7.10, and you got other mods for different versions like 1.12.2, it will crash, make sure to take out the other mods then try loading your mod again! :D

For me, i have only mods of the exact same version in the folder, Noppes Custom NPC's.  
The error messege says it has no idea what the error could be, but here is the gardle console log:

I do have something actually! If you use the play mod feature in the top right, you could also build up the mod, export it to your mods folder, close mcreator for the time being, and open it in actual minecraft! Of course this means you need to downloaf it but its nothing to bad
