Error: multiple platforms feature is currently not supported for docker driver

Hey, no need to completely wipe your Docker Desktop!

I ran into the same/similar Issue today after Upgrading to Docker-Desktop 4.14.0 (91374) on M1.
Buildx starts complaining with this (no issues running the identical command the day before):

$ docker buildx build --no-cache --platform=linux/amd64,linux/arm64/v8,linux/arm/v7 -t <repo>:latest --push .
[+] Building 0.0s (0/0)
ERROR: multiple platforms feature is currently not supported for docker driver. Please switch to a different driver (eg. "docker buildx create --use")

I just recreated a new Buildx Instance using the docker-container driver, tell Docker to use it and it started working again :slight_smile:

$ docker buildx create --use desktop-linux
pedantic_goodall
$ docker buildx ls

Of course you can tweak a bit more using docker buildx create --use desktop-linux
