Pladio,
Are you using a mod managing tool like Nexus Mod Manager or only the (not) good and old Steam Workshop, in order to have XCOM2 heavily modded like that?
I used the Steam workshop, but what I did first was to unsubscribe from all (using Steam), deleted all the config folders and verified game integrity after that.
I did this because at first the game did not run as I think there were some previous configs saved that broke everything.
Then I used ChrisOdd's modlist (https://steamcommunity.com/sharedfiles/filedetails/?id=1328549637) and subscribed only to those that interested me. For example "World War L" did not interest me, because I do not enjoy the Lost and making them harder felt like a way to reduce my enjoyment. The looks are cool, but it doesn't say how to disable the new Lost monsters and so I did not include them.
The last step was to look through some mods that I would enjoy and I loved playing with Grimy's loot mod when I played last year so I included that. I then also included I think only 4 others (TheAxeMod, WotC Mod Everything Reloaded, WotC Infiltrator Primary Secondaries).
Essentially, the list of Chris should all work as he's playing on YT with it. Any additions would be at your own risk.
Saying all of this, I did try downloading a "mod launcher", but it doesn't seem to work very well. It was helpful in creating the list I made for you up above, and it shows if there are any potential conflicts, but it doesn't seem to launch the game on my computer.
