DLC pop ups on start up

I'm sure it's not just me, and not just happening to Mac users, but I'd say about 20% of the time I start my game up, there's an initial full-screen pop up related to a new DLC that, once closed, my Main Menu screen shows as darker/almost ghosted out. I can't click anything. I can, however, still exit the game and reopen, as opposed to force quit. It's sort of a roulette situation when it comes to closing out the DLC pop up and seeing a normal menu screen vs a dark unclickable one. Not a huge deal but it is inconvenient, unpredictable, and literally unavoidable.

Mostly annoyed because I installed a mod (this was happening before I had any mods in game, by the way) and I already know I need to restart my game after I tune some settings in that newly installed mod. This bug slows the entire process down of installing and adjusting mods, then proceeding with required restarts, as it makes each start up potentially unviable.
