Running Docker Desktop 4.19.0: docker build with --platform flag - no match for platform

[wbreza]

• [x] I have tried with the latest version of Docker Desktop
• [x] I have tried disabling enabled experimental features
• [ ] I have uploaded Diagnostics

Actual behavior

Running docker build --platform amd64 . fails with error:

Output

Running docker build . without --platform flag works as expected.

Expected behavior

docker build command should work since amd64 is a supported platform

Information

• Windows Version: Windows 11 Pro (10.0.22264)
• Docker Desktop Version: 4.19.0
• WSL2 or Hyper-V backend? WSL2
• Are you running inside a virtualized Windows e.g. on a cloud server or a VM: No

Steps to reproduce the behavior

1. Create Dockerfile with the following:

# Dockerfile simple example. 
# Repros with any image that supports arm64
FROM nginx:alpine

WORKDIR /usr/share/nginx/html
EXPOSE 80

CMD ["/bin/sh", "-c", "nginx -g \"daemon off;\""]

2. Run docker build --platform amd64 . in same directory as Dockerfile

Update: Works with full os/arch specified. Works: --platform linux/amd64 Fails: --platform amd64 (Previously worked in versions < 4.19.0)

I met similar error outputs on Intel macOS (11.x) with --platform linux/arm64. After downgrading to 4.18.0, everything works again.
