At least that's my experience.
Went from 20 mods to almost 200 and had a bit of a fright when the window froze.
Leaving this notice for others.

need time to load hundreds mods. Close to 1 min to enter the game on SSD. The game need longer time to regenerate the config when load first time or change mods.

Normally, I'd agree, but it's taking far too long to start. Think there is a problem. I'm getting a notification about mizirukis perk pack (sp?)

I'm also having issues with just these mods. With the basic collection loaded it boots up fine. Once I subscribe to the rest of the list it will freeze on loading. I do have an SSD and have waited 5 - 10 minutes to no avail. I'm thinking there is an issue.

Definitely worth looking into. On my main desktop, it takes around 100 seconds to start, my laptop takes around 180. Cosmetics will also significantly affect this time too. If you're hanging, you can add the -log argument (similar to how you enable console) and it will open a second window with the log, so you can see where it is hanging.

So this is in the log after the Checking DLC installation section. Can you make heads or tails of it?

EDIT: This is with the Basic collection, Ted Jam+, and the Requiem Legion Tweaks collection. No classes and no additional mods added. Also to note, I've been using AML for a long time and this is the first time I've had an issue loading mods. I've been running Covert Infiltration for years and thought I'd try something different for a change.

EDIT 2: Problem solved I guess? Uninstalled game, deleted XCOM 2 docs and install folder, reinstalled game, redownloaded everything and it works. Don't know why it fixed it but I'm glad it did.
