Sims 4 help!

Hello! I am having this issue where this white bar that says "the sims 4" is stuck at the top of my screen. When I'm actually in the game it's unplayable because it blocks the whole top of the screen - it's also just annoying to have on the screen 24/7. I have read online that it is stuck in windowed mode but even when I force it back to full screen mode it stays and when I go in windowed mode another bar pops up like the game is not registering the bar is already there. I have done almost everything I have seen online (like alt + enter) and I am just at a loss now. I have even uninstalled the whole game and reinstalled. I do play with mods but it's all up to date and so is my game. Any help is deeply appreciated!
