Hi, I am Dave, I will help you with this.
The most compatible version of the Realtek drivers for your PC are the ones that you can donwlaod from the support page for your PC on the manufacturers website.
If you have any problem locating that support page, click your Start Button, then just type msinfo and press Enter, please provide a screenshot of the resulting System Information window.
The problem is that there is not a Windows 11 download
