Windows 10 GPU No devices found

[nothing]

Hi,

I'm having issue with the latest version of hashcat to use my GPU on Windows 10 1903. I'm using this command in powershell .\hashcat64.exe -b -w 4 -D 2 but I get this error "No devices found/left".

Here more information :
Hashcat 5.1.0
Vega 56
Intel i7 9700k
AMD 19.5.1 driver

Could anyone please help me to get hashcat working with my GPU.

Thanks
