Prep Connect -> Object Not Set error

Describe the bug In Visual Studio 2019, Bridge To Kubernetes doesn't start anymore. I have a service in my local Docker Desktop cluster (default namespace). I tried to connect to it after setting all the right values in the configuration page (Kube Config Cluster: docker-desktop, Namespace: default, Service: , no routing isolation, application url : http://localhost:7778). When I try to launch the Bridge To Kubernetes debug, I get an "Object not set to an instance of an object" infamous error. It didn't prompt me for elevated permissions so that what seems to be the cause but I have no clue how to fix it. I looked at previous threads but can't seem to find a straight answer.

UPDATE I just noticed the known issue about the presence of headless services in the cluster that may impact connection. As a matter of fact, I do have 2 MongoDb headless services in the cluster (mongodb-headless and mongodb-arbiter-headless). Maybe that's the problem.
