DirectX 9 is a problem for anything that relies or uses it, including apps, PowerPoint presentations, browsers and some websites. Microsoft has confirmed the issue. The latest version of the software is available. Microsoft has added this error to its list of known issues. The issue persists, causing frustration for users. Some have to reset their builds in order to get Windows 11 to work again.
What you can do, if you are affected
Some people were able solve the problem or at least contain it by replacing the D3D9 DLLs in the System32 folder and SysWOW64 folder with files from older builds. This can only done with admin privileges via PowerShell and requires deactivating Nvidia GPU from the Device Manager.
The problem is only affecting those who are in the Windows Insider Program and have Canary builds. Microsoft has not explicitly stated that Nvidia graphics cards are the cause of the problem, but it appears to only affect Nvidia graphics cards.
