Docker Desktop throwing Fatal Error at Startup on MacPro M4

It is actually 4.43.1 now. You could try that. There was a similar bug report years ago

You could also search for “com.docker.driver.amd64-linux” among issues on https://github.com/docker/for-mac/issues. It seems there were some, but not recently, so you can create a new issue if you see your issue is different.
