Client wont run, no feedback on console.

Whenever I hit "Run client" my Mcreator freezes and Minecraft doesn't load.

I recently did the following since this started happening:

Added colored blocks called "borders" "border1" "border2" etc. I have all the textures but only implemented two. They are unbreakable stone sounding blocks.

Recipes for some blocks such as "Barrackslvl1" "barrackslvl2" "barrackslvl3"

And created a weapon called "Gun Chainsaw" a joke item, since this issue started it has been deleted.

I've had other issues, but I have been unable to troubleshoot it, any advice?
