@azfar90my Does the Steam overlay work in other Steam games? If you own any, please test.
Please also change the key binding for opening the Steam overlay; by default it conflicts with a Sims 4 key binding. You can use whatever keys you want, but try a couple different combinations that (to your knowledge) don't do anything else on your computer.
I tested with Mass Effect Andromeda, Battlefield V, Need For Speed and Mirror's Edge Catalyst, whether with default key binding or even custom binding, I can open the Steam Overlay like normal and Steam can even track that I play those game where its says "Running", except for The Sims 4.
@azfar90my I tested myself just now, and I can also bring up the Origin in-game overlay even with it disabled and with Origin in offline mode. If I click on any of the options though, I get an error. So it seems that the overlay itself doesn't get disabled, just all of its features.
For Steam, please double-check that its in-game overlay is enabled specifically for Sims 4. It's possible Steam disabled it by default at some point, especially since it conflicts with the key binding for first-person mode. If that's not the issue, can you bring up any elements of the overlay while you're playing? Alt-tab back to Steam, click View, and choose a couple of the windows. I know it's not as convenient, but I'm curious whether this works or not.
