Does this occur consistently?
Repro steps:

$.createCognitiveServiceAccount extension.js:2148:26225
async a.newProjectWithAccount extension.js:2390:19325

Start with the ai-mlstudio.viewContext.switchDefaultProject action and the createCognitiveServiceAccount/newProjectWithAccount stack locations in extension.js:2148 and extension.js:2390. Reproduce the 409 on Windows with the reported subscription state; done should be a confirmed, actionable outcome for the missing Microsoft.CognitiveServices registration rather than an unresolved generic failure.
