Windows 11 installed Version 24H2 on my PC. Since that installation I cannot start D3, I keep getting the message "Diablo III was unable to initialize D3D. I have restarted my PC numerous times and still get the message. I also tried uninstalling and reinstalling D3, still get the same message.

There are other steps you can try here:
One player on the French forums was able to get the game launching by modifying DisplayModeWindowMode from 0 to 1 in the D3Prefs.txt file… essentially, by launching the game in Windows Mode.

@MrNicke: Hello,
Just want to ensure that I understand what you did to fix the issue on your system…
Are you saying that you only used the “Reset In-Game Options” button (shown under) and that you could launch D3 afterwards without issues ? Are you launching in Windowed, Windowed (Fullscreen) or Full Screen Mode ?
Thank you for any details you can add…

A similar problem occurred on my computer after installing Windows 11 24H2.
Native resolution of my monitor is 2560x1440.
When I used this resolution in the game settings, there was no problem.
But when I set it to a higher resolution (scaling, DSR: 3620x2036), this problem appeared.
For me, in the “nVidia control panel” settings, “Manage 3D settings”, selecting game “Diablo III”, and setting “Image Scaling: On” solved the problem.
Worked for me. Thank you!
This worked for me thanks
As of 1/21/2025, this worked for me too!! Thanks bunches!
