Unstable OpenCL driver detected!

[scriptkiddy]

I have Intel UHD Graphics 620 graphic card and i am using windows 10 20H2 version
I downloaded "OpenCL Runtime for Intel Core and Intel Xeon Processors" and in addition with this i also downloaded
"Intel graphic runtime for OpenCL" and read almost 10-20 solutions on the web struggled for more than 5 hours at a time. Struggling to find solution from last 2-3 days but nothing worked for me yet thats why am posting it here please help me.
Whenever i use hashcat it says unstable OpenCL driver detected . I also read the hashcat 'wrong driver' thread uninstalled all drivers and installed them again but that too not worked for me.
It uses only my CPU to crack pass and thats very very much slow about 8k H/s. 

when i use command Hashcat -I it give following result 

* Device #1: Unstable OpenCL driver detected!
