Why I am getting this error when executing docker version with non-sudo user. I have installed docker using Script

Cannot connect to the Docker daemon at unix:///home/cttc/.docker/desktop/docker.sock. Is the docker daemon running?

My user is part of a docker group. Previously, there is an installation of docker desktop but I have uninstalled it.
Since my suspicions in the comments were confirmed, I am here writing it up again.
The docker version
command put out the context for the non-root user as
Context: desktop-linux
and for the root user as
Context: default
This discrepancy put me on the right path. Using docker context show
intuitively shows the current docker context in which the program works. These contexts were confirmed to be different for the different users.
Docker contexts can be switched with docker context use <context name>
, so here default or desktop-linux.
