Automation marked Active but does not run or create a thread

Summary
On April 6, 2026, my automation did not run at its scheduled time. The automation is marked ACTIVE, but no new thread was created and no visible execution started. Note, that I have the Windows version of ChatGPT Codex that is available through the Microsoft Store

Automation details
Status: ACTIVE
Schedule: daily at 2:15 PM Eastern
Execution environment: worktree

Expected behavior
At 2:15 PM EDT on April 6, 2026, the automation should have:

• started automatically
• created a new thread
• executed the prompt
• produced visible run output

Actual behavior

• no new thread appeared
• no visible run output appeared
• the automation remained marked ACTIVE
• the scheduled run appears not to have started

Local evidence
Workspace shows:
status = "ACTIVE"
rrule = "RRULE:FREQ=WEEKLY;BYHOUR=14;BYMINUTE=15;BYDAY=SU,MO,TU,WE,TH,FR,SA"

I could not identify a clear local trace of a run starting for this automation on April 6, 2026

Reproduction steps
Create or keep an automation active
Configure it to run on a daily schedule
Wait for the scheduled run time, or click Run now
Observe that no thread is created and no visible execution starts

Notes
This looks like the automation runner is failing before task execution begins. The issue does not appear to be specific to the automation prompt itself, since the symptom is that no thread or runnable task is created at all.
