xcom2-launcher VS In-Home-Switching

If you're not using the Alternative Mod Launcher you should

Get Alternative Mod Launcher. https://github.com/X2CommunityCore/xcom2-launcher/wiki

It's weird that verifying files doesn't work. Try renaming the config folder in user/documents/my games/xcom/xcomwotc, when you launch the game it should regenerate the folder and maybe it'll run properly. Also, even if you don't use mods try the Alternative Mod Launcher, the 2k launcher is garbage.

I've never used the 2k launcher but I've heard from modders that it's so useless that sometimes it fails to even load the game, don't even think of loading mods with it. I don't know if this is your problem but you can try to use the Alternative Mod Launcher, of course you don't need to actually load any mods, just use it to launch the game, maybe that will work

You shouldn't be using the 2k launcher, use the AML instead, if it doesn't find the mods go into settings and add the folder to the list

Check this sub's wiki, at the bottom it shows you how to set up a local mods folder, then you should add that folder to AML, which you should be using for modded XCOM 2

Dude, the og launcher Is shit; you gotta use the AML if you wanna play X2 decently. AML stands for Alternative Mod Launcher, and it's an X2 launcher built by the community to make mod management easier (and since the various launcher updates, keep the game running as well...) You can find it here on GitHub: https://github.com/X2CommunityCore/xcom2-launcher

Download the Xcom Alternative Mod Launcher from here: https://github.com/X2CommunityCore/xcom2-launcher

Are you using the AML ? It will tell you if there is any conflicts, tho it can't show all the problems that your list might have
