Edited by blizzard: This message requests system reports and error logs, but we have received enough. Thank you for the information to help us identify the problem!
Hey, DavisX! We aren’t aware of any issues with Windows 10 Version 2004 for Diablo III yet, but I’ll take a look around to see if we have any information about the 2004 update. Since the FMOD errors are usually tied in with the audio, which you’ve already tried many steps for already, let’s gather a bit more information on the situation.
@CallMeRED, could you also check if the same FMOD errors are happening within the D3Debug file? This is located in the installation location. Go to the Blizzard Application, then the Diablo III tab. Click on Options > Show in Explorer. You should see a ton of files, but the D3Debug.txt file is located within the Diablo III folder.
Could you both provide a DxDiag file. Copy and paste the text file created and paste it between two ~~~ like so:
