Docker not starting up after installation – Ubuntu

I tried installing Docker in windows 10; I activated WSL and virtualization in windows features too, and also installed the latest ubuntu distro.

But when starting docker it holds on for little bit longer than usual and says "failed to start docker".

Following is first error I got:

Docker.Core.HttpBadResponseException:
{"message":"1 error occurred:nt* starting WSL integration service: synchronising agents: starting added distros: 1 error occurred:nt* waiting for WSL integration for Ubuntu: timed out while polling for WSL distro integration to become ready in "Ubuntu"nnnn"}

And then on later tries the error I got was different:

Docker.Core.HttpBadResponseException:

I have tried most of the things I searched online. I uninstalled, shut down the pc and installed again as admin; all in vein. And yes, I also enabled WSL2.

Then I again uninstalled and cleared all docker folders on the system and re-installed, shutting down and installing. No difference.
