brayleighms The issue here is that it's difficult to say whether this is purely a save issue, or only partly a save issue and partly a system issue. Five seconds of delay in one save vs. none in a new save is a strong suggestion that something about the main save is the problem. On the other hand, it's still possible that this save is taxing your system enough to bring out these symptoms where a new save does not. So I'd like to go at this from both angles, at least for one more round of troubleshooting; feel free to complete these steps in whatever order you like.
For the possible save issue, please try playing a different household within this save, preferably one you haven't played before. If that household is fine, have them visit your main sims. If that's fine too, switch back to your main sims and see how long it takes for the delay to reappear. You don't have to save your progress through any of this.
Separately, please save your main sims to your in-game library and place them in a new save. Quit to desktop before loading that new save. Let me know how it runs.
For the system side, your current dxdiag lists a number of somewhat-generic Windows errors. So regardless of the results of the tests listed above, please run a couple of basic checks of your Windows system files:
- Hit Windows key-X
- Choose either “PowerShell (Administrator)” or “Windows Terminal (Administrator),” whichever option is offered
- Inside the window that appears, copy and paste “DISM.exe /Online /Cleanup-image /Restorehealth” without quotes, and enter
- The system will start validating soon. If it throws an error, please list it here
- After it reaches 100%, hit Windows key-X again
- Again, choose “PowerShell (Administrator)” or “Windows Terminal (Administrator)”
- Inside the window, copy and paste “sfc /scannow” without quotes, and enter
- Post the message you receive here
Restart your computer, hit Windows key-i, select Update & Security, and click the box to check for updates. If any install, restart again afterwards.
If you're seeing this same delay in clicking in any instance other than the original one (your main sims in your old save), please try playing in a clean boot:

The one service to leave enabled is the EABackgroundService, which the EA App needs in order to run. Disable the rest as described.
When you reboot your computer, go through the Task Manager's background processes list shutting down any service that doesn't absolutely need to be running, for example anything from MSI Afterburner to RGB software might still be enabled. If you accidentally kill a critical process and it doesn't restart on its own, just reboot your computer again.
Don't open anything other than Sims 4 and the EA App while testing, not even a browser window. If the clean boot itself doesn't help, repeat the test except with your computer offline. You can sign into the EA App and put it in offline mode, then disable wifi and/or disconnect the ethernet cable before pressing Play.
I realize this is a lot, but since the basics haven't helped and nothing in your dxdiag or LE points to an obvious problem, it might take some digging to get to the bottom of this.
