Sign Tool for Azure Trusted Service Account Error information: "Error: SignerSign() failed." (-2147467259/0x80004005)

I'm getting this error when trying to use SignTool to sign my msix file.

I've verified I have Trusted Signing Certificate Profile Signer role assigned in Azure.

I also verified the publisher name of the AppxManifest.xml in the msix matches my certificate profile.

CN=Publisher Name, O=Organization Name, L=City, S=Province, C=CA

Following this procedure https://learn.microsoft.com/en-us/azure/trusted-signing/how-to-signing-integrations

Solution

The issue was my authentication "InteractiveBrowserCredential" was not working for some reason. I had to disable all authentication options except Azure CLI and retry. https://learn.microsoft.com/en-us/cli/azure/install-azure-cli.
