TL;DR

The issue might be resolved by investigating and addressing the high memory and CPU usage of the Codex App after the latest update.

Guidance

  • The high memory and CPU usage could be due to a bug or inefficient code in the latest update, causing the app to consume excessive system resources.
  • Try to check if there are any other resource-intensive processes running in the background that might be contributing to the issue.
  • Consider reaching out to the Codex App support team to report the issue and ask for their assistance in troubleshooting or providing a potential fix.
  • If possible, try to gather more information about the system's specifications and usage patterns to help identify the root cause.

Example

No code snippet is provided as there is no clear indication of a specific code-related issue.

Notes

The provided information suggests a potential issue with the latest update of the Codex App, but more details are needed to determine the root cause. The fact that deleting the app and wiping out cache did not help suggests that the issue might be more complex.

Recommendation

Apply workaround: The user may need to wait for an update or patch from the Codex App team to address the issue, or explore alternative solutions that do not consume excessive system resources.
