Cannot Access Dashboard / Duplicate Key Error After GitHub Migration (Account Auth Issue)/Persistent Auth Error (mika2525-code)

Dear Streamlit Support Team,

I am writing to report a critical authentication issue preventing me from accessing my application dashboard and making necessary deployments.

**Context:**

1. I recently created a new GitHub account (Username: mika2525-code) and successfully migrated my application code to a new repository (Repo: mika2525-code/cbt-app) to resolve previous credential errors.

2. The code push via SSH was successful, confirming the repository exists and the code is up-to-date.

3. However, when attempting to access the dashboard or deploy a new app from this repository, I receive the error: **“You do not have access to this app or it does not exist.”** This happens even though I am logged in with the correct GitHub account.

**Problem:**

The core issue appears to be that the Streamlit Cloud platform still has a corrupted or conflicting link to my GitHub account/old app history, which prevents the new, correct repository from being read. I cannot proceed with the deployment.

**Goal:**

Please investigate the link between my `mika2525-code` GitHub account and the Streamlit Cloud service and reset any conflicting access tokens or deployment history so that I can successfully deploy my application.

Thank you for your prompt assistance.

Sincerely,

Mika Matsui
