(Azure DevOps only) What format is your remote URL?

None

Can you access the remote repository directly in the browser?

Yes, I can access the repository

Expected behavior

There are 2 expected behaviors that are not happening.

1. There should be no auth prompt in the first place. I have the following GCM config set:

[credential]
	interactive = auto
	azreposCredentialType = oauth
	msauthUseBroker = true
	msauthUseDefaultAccount = true

as well as

[credential "azrepos:org/<ORG>"]
	username = me@contoso.com
	azureAuthority = <AUTHORITY_URL>

On this same machine, in this same state https://aka.ms/azureauth doesn't need to prompt and uses the current OS account without issue.

2. GCM is launching an auth prompt, and that prompt should render an allow me to continue with the auth flow.

Actual behavior

1. Silent auth via broker isn't happening.
2. The prompt renders an empty window frame. The program icon is shown on the task bar, and the window frame outline is there, but the body is transparent and empty.

Start by reproducing the empty authentication prompt and missing silent broker authentication on Windows 11 ARM64 with GCM 2.4.1, using the configuration and Azure DevOps setup described here. Compare the prompt rendering and broker behavior with the expected OAuth flow; done means silent authentication works or the prompt renders usable authentication controls.
