Halo 5 Forge App Issues

Ok, I’ll be straight to the point.

App: Halo 5 Forge for Windows

My Specs:
Laptop: Acer VN7 Nitro Black Edition Limited Edition
Processor: Intel Core i5-6300HQ CPU @ 2.30GHz
Ram: 8BG
System Type: 64-Bits
GPU: Intel 530
Secondary GPU: Nvidia GeForce GTX 960m 4GB GDDR5 VRAM and everything is running by using this graphic card as default.

Okey, here is my problem, since a long moment, I am trying to make real good custom games into Halo 5 Forge App but I have an issue or maybe 2. The chat box only works once then after that, it freeze and I have to screw up everything. The second problem which is my priory issue is the game close at desktop everytime I am loading a big custom map from my save files. My OS is clean top notch and seriously I can’T find a way to fix tha issue. So if anybody can tell me how to fix it just let me know.

I forgot, reseting Halo 5 does nothing and it don’t solve my problem.
