7/23 Update messed up my mouse

Product: The Sims 4
Platform:PC
Which language are you playing the game in? English
How often does the bug occur? Every time (100%)
What is your current game version number? The latest version, updated yesterday.
What expansions, game packs, and stuff packs do you have installed? All of them.
Steps: How can we find the bug ourselves? Cursor is bouncing to other monitor.
What happens when the bug occurs? I’m using a laptop with a monitor attached, with sims 4 open in windowed mode on the monitor. When I move the cursor to the right side of the screen (display 2), the cursor jumps to the middle of my laptop screen (display 1). If I have the sims in windowed mode on my laptop (display 1), this doesn’t happen. All other apps and programs are working perfectly without this issue, and I have always been able to play the sims this way with no problems prior to this update.
What do you expect to see? I expect to be able to use my second (much larger) screen without issue.
Have you installed any customization with the game, e.g. Custom Content or Mods? Not now. I've removed them.
Did this issue appear after a specific patch or change you made to your system? Yes
Please describe the patch or change you made. I installed the latest game patch.

I’ve restarted the computer and the game multiple times and still having the same issue. Mods and CC were all removed prior to updating the game.
