You are fine.

For any problem just feel free to add me on steam, so i can help you out

I arleady gave this feedback in the proper bug reporting section.
What is causing crash? Probably you tweaked the graphic settings like me and deleting the configuration files will fix the problem
I have done these steps and i fixed my issue.

My MCC Insider crashed the one time I tried to load it. Since then my regular MCC freezes than crashes every time I try to enter the game after the loading screen. Is this related?

Did you try reinstalling/repairing the Easy anticheat? i think its related

D:\STEAM\steamapps\common\Halo The Master Chief Collection Flighting\installers here you can find the easyanticheat.exe
Same directory location is for the MCC edition (non the flight)
