On Windows 10, Docker Desktop (Docker Engine v20.10.17, WSL enabled and running properly) fails to docker build an image (that, btw, works properly on Debian 11) throwing following error:
docker build -t <image-name> .

A similar case was answered here, although the solution doesn't apply in my case. Searching the web yielded several similar (but not identical) cases with different solutions (including a reinstall), which all failed to solve this.
In the end I found a (or the) solution in the Docker forum:
in Docker Desktop, navigate to Settings > Docker Engine, change buildkit to false in the Docker daemon configuration file and then click "Apply & Restart".
