It won’t be an answer, just some notes to help you clarify your issue. You created your topic in the Image Builds category. You even added the “build” tag" and also “windows-containers”. That doesn’t make sense after reading your message since you meniton no image builds and no windows containers, only Ubuntu.
We usually need the following information to understand the issue:

docker info docker versionReview the output before sharing and remove confidential data if any appears (public IP for example)
dpkg -l 'docker*' | grep '^ii' snap list dockerWhen you share the outputs, always format your posts according to the following guide: How to format your forum posts
