This should only happen on the dev branch.

It is triggered here:

azure-cli/src/azure-cli-core/azure/cli/core/auth/msal_authentication.py

Lines 43 to 45 in 6442bed

	if len(accounts) > 1:
	raise CLIError("Found multiple accounts with the same username. Please report to us via Github: "
	"https://github.com/Azure/azure-cli/issues/new")

The corresponding change on MSAL is AzureAD/microsoft-authentication-library-for-python#349

Please run azdev setup to re-setup the CLI dev environment which will bump MSAL and see if the issue gone.

It works after executing azdev setup again.
