Gadget+ Mod crashes at launch

We use our xboxone so im not sure what version above so I just picked one. We purchased the gadgets + mod. Everytime we try to launch it the Minecraft game crashes. The mod isthe only one thats doing this when we try to play. Gadget + was purchased using Miecraft Marketplace. My son was so looking forward to play. Also we have noticed a heavy increased lag. Please look ito this mod and lag issues please and thank you!
