Description

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

26.810.41047 (6570)

What subscription do you have?

PLus

What platform is your computer?

Mac: Apple Silicon

What issue are you seeing?

ChatGPT/Codex desktop app crashes consistently approximately 2–5 minutes after launch.

Version: 26.810.41047 (6570)
macOS: 26.6.1 (25G76)
Mac: Apple Silicon

The app worked normally on Friday 14 August. The issue began on Monday 17 August.

Every launch now results in a crash after a few minutes.

Crash report contains:

Dispatch Thread Soft Limit Reached: 64 (too many dispatch threads blocked in synchronous operations)

There are repeated calls involving:

sky.node
RemoteHostedPIPContentService
AESendMessage

I disabled the Computer Use integrations for Chrome and Excel and completely restarted the application, but the crash still occurs.

The latest crash occurred approximately 2.5 minutes after launch.

What steps can reproduce the bug?

Simply by opening up the ChatGPT app and leaving it, after a few minutes it crashes

What is the expected behavior?

Research direction

Start with the supplied crash report details, especially the Dispatch Thread Soft Limit and repeated sky.node, RemoteHostedPIPContentService, and AESendMessage calls. Reproduce by launching the ChatGPT/Codex macOS app and leaving it open for several minutes, then compare the resulting crash behavior with the reported 2–5 minute timeframe. Done means the app remains open without repeatedly crashing under the same conditions.
