Blank GUI window after update on macOS Tahoe (Apple Silicon) while CLI works normally

What version of the Codex App are you using (From “About Codex” dialog)?

26.422.62136 (2180)

What subscription do you have?

Plus

What platform is your computer?

Darwin 25.4.0 arm64 arm

What issue are you seeing?

Symptoms:

Codex GUI launches, but the window is completely blank/empty
CLI works perfectly
Authentication works
Network/proxy works
No crashes visible in CLI mode

I launch Codex through proxy environment variables:

http_proxy=http://127.0.0.1:8118
https_proxy=http://127.0.0.1:8118
all_proxy=http://127.0.0.1:8118

CLI launch command works correctly:

"/Applications/Codex.app/Contents/Resources/codex"

GUI launch command opens an empty window:

"/Applications/Codex.app/Contents/MacOS/Codex"

Relevant logs:

[electron-message-handler] [startup][renderer] app routes mounted
[electron-message-handler] Handled 'ready' message, sent ide-context-updated

and repeatedly:

unsupported feature enablement workspace_dependencies

I already tried:

clearing ~/Library/Application Support/Codex
clearing caches
reinstalling Codex
removing runtime cache
resetting Electron state

The issue started only after the latest update.
CLI remains fully functional.

What steps can reproduce the bug?

Latest update

What is the expected behavior?
