--> uninstalled and installed again, that also not worked.
--> tried on windows Os build - 17134.285 and 17134.320, for both not working

--> where as its working on another device of mine.

Hi @gouravtayal,
Can you provide additional information on the device that you're using, e.g. hardware configuration, and try the following -
Hi @hassanuz
please find the attached screenshot for hardware configuration

.
Make sure developer mode is enabled in the "For developers settings" in Windows settings
@cjkeilig developer mode is enabled.
Hi @gouravtayal,
Were you able to open a feedback item in the networking area (repro'ing the problem with logs attached)?
Please do this if you have not already as this will definitely help us further investigate this.
Thanks
@gouravtayal I had this same issue. It appears to be an issue binding to the IP Address and Port. I found the following error in Event Viewer:
The HTTP Service service failed to start due to the following error: The configuration registry database is corrupt.
A quick Google search presented this solution on StackOverflow: https://stackoverflow.com/a/47702775
I also found an empty key in my registry and removed it, then I was able to start WinAppDriver.
@DevinSanders64 Thanks for your input, i tried the steps mentioned by you. But it also not worked for me.
