I had a similar error message ("Cannot find container to attach, check if the container is running or not").

In my case I upgraded my project from net6 to net8 and after that the error occurred.

What didn't help:

• restarting Docker
• removing all (old) project related containers and images
• removing the .vs folder

What did help:

• recreating the Dockerfile (by deleting the old one and adding Docker support again). In the Dockerfile there is also a reference to framework version so that might be the reason that it didn't work in the first place.
