Title: ChatGPT Desktop App v1.2026.133.0 - Login button unresponsive, chats don’t render, browser works normally

Environment

  • Windows 10 Pro 22H2 (Build 19045.6466)

  • ChatGPT Desktop App: 1.2026.133.0 (Microsoft Store)

  • Microsoft Edge WebView2 Runtime installed

Issue
After updating to version 1.2026.133.0:

  • Login and Sign Up buttons do not respond.

  • Existing conversations do not open.

  • New prompts can be entered, but no response is rendered.

  • Browser version works normally on the same machine.

Troubleshooting already performed

  • Uninstalled and reinstalled the app.

  • Cleared LocalCache, LocalState, and TempState.

  • Verified WebView2 installation.

  • Ran sfc /scannow (corrupted files repaired).

  • Ran DISM /Online /Cleanup-Image /RestoreHealth successfully.

  • Restarted the PC.

  • Other desktop applications work normally.

This appears to be a regression specific to ChatGPT Desktop App version 1.2026.133.0.

I can reproduce this issue consistently on Windows 10 Pro 22H2. Browser works normally. SFC and DISM completed successfully, WebView2 is installed, and reinstalling the app did not resolve the issue.
