Sims 4 ingame gallery freezing [SOLVED]

Every-time I open my Sims4 gallery, click what I want to, look into/download/favorite a gallery lot/sim someone uploaded, It gives me this screen (faded, still dark) and it freezes my Sims4 and I cannot X out of the game. (Close through task manager) Does anyone know what could be causing this? I saw others had the same problem but no solution.

-I do have custom content and some mods, I cleared my mods the other day but I could go through my custom content and see how that goes.

-I have a gaming PC with a 1070 GTX graphics card so I know it isnt my computer (My specs are fine and its been working properly until just recently, so maybe I'll just remove the recent custom content I have downloaded?)

SOLVED!  I had to update my UI Cheat Extension Mod!
