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

26.527.31326

What subscription do you have?

PRO

What platform is your computer?

Microsoft Windows NT 10.0.19045.0 x64

What issue are you seeing?

UI is bugged. I previously saw some Electron errors ("not found" errors), and now I am seeing this launch error when running the Codex app. The app still works, but the errors continue to appear.

UI bug: the left sidebar with chats and projects is semi-transparent(in full screen mode)

P.S. Сomputer use and mobile connection features are not working.
