4090 notebook GPU, no hashcat

[RT@TGT]

Greetings all!
Been awhile since this has been update but FEAR NOT!

I bring you a workaround that appears to solve this issue on Windows 11.
Major shout out to "Unspecified Principal Engineer" (his words, not mine)

First off, seems to be an issue with OpenCLOn12, "a mapping layer, which implements the OpenCL 1.2 API on top of D3D12. It also implements the OpenCL ICD extension, and can therefore be loaded by the existing ICD loader."

Ref Link: https://github.com/microsoft/OpenCLOn12

Workaround: Remove Offending Program

Open PowerShell as Admin
>

Code:

Get-AppxPackage -Name Microsoft.D3DMappingLayers

Look for the following line:

Code:

PackageFullName  : Microsoft.D3DMappingLayers_1.2302.1.0_x64__<more stuff>

Copy the info from that line and paste into following command:
>

Code:

Remove-AppxPackage -Package <Package_Full_Name from Above Command>

Reboot and give it a try.  I was able to run examples, backend info mode, benchmarks, etc.  All not functioning before.

Thank you again to this community for your insight and assistance.
Greatly appreciated!
