To me it seems to confirm a huge issue with the new Launcher 2k (or Faixas) put out there. The Alternate Launcher does the same thing that opening the old Launcher does. I can confirm that the Alternate Launcher does work. So instead I went through my computer to find the XCOM2 Alternate Mod Launcher and tried that. In my case that method did not work unfortunately. So doing what Arckie said and his steps is simply allowing you to load up the old launcher and launching the game with the launcher that works.
Not sure if people are having issues with none of their mods working or not. For me every mod before the new launcher works anything after is not. With this new Launcher it seems to have a bug that every mod downloaded after this updated Launcher is not activated. The issue seems to be something wrong with the new launcher for XCOM 2 that looks like they just launched at the same time they released the Nintendo Switch version. Little information from what I gathered about this whole mess.
