This has been around since S22 at least. It’s due to FMod and a windows change. Here is a post that explains what happens and shows the D3Debug.txt log showing the error. The fix was replacing the D3 FMod with the Heroes of the Storm FMod, and living without sound. Hopefully Blizzard can give us a better permanent fix. Wudijo and Leviathan and many other content creators have posted fix videos on youtube for this bug.
