TL;DR

The most likely fix is to investigate and resolve the regression introduced in version 1.3883.0 that breaks the event path from LocalSessions.setAutoFixEnabled to AutoFixEngine.

Guidance

• Review the update process and version history to identify potential changes that could have caused the regression.
• Check the main.log for any related errors or warnings that may indicate the root cause of the issue.
• Verify that the LocalSessions.setAutoFixEnabled events are being sent correctly and that the AutoFixEngine is properly configured to receive these events.
• Consider downgrading to version 1.3561.0 to see if the issue is resolved, which could help confirm if the problem is indeed related to the update.

Example

No code snippet is provided as the issue seems to be related to a specific version update and configuration rather than a code-level problem.

Notes

The provided error logs seem unrelated to the main issue of AutoFixEngine not responding to LocalSessions.setAutoFixEnabled events, as they mention different errors such as "Tool TodoWrite not found" and "Lock acquisition failed". The actual cause of the regression might be hidden in the truncated part of the log or in the update process itself.

Recommendation

Apply a workaround by downgrading to version 1.3561.0 if possible, to immediately restore functionality while the root cause of the regression in version 1.3883.0 is investigated and fixed.
