Same issue, even trying to reinstall it doesn't work. This is on my Macbook Air. On my Macbook Pro for work there isn't any issues though.

Hi @YousefAbuJalboush , @HammerAndShield. Sorry for this causing you trouble.

We'll give a test locally to figure out what happened. Do you mind to share

• which version do you used before upgrading to 0.35.0
• the entire log located at ~/Library/Logs/GitHubCopilot/github-copilot-for-xcode.log.

This is really helpful.

Here is one possible walkaround - To remove the settings and historical data of GitHub Copilot for Xcode:

1. backup the data located at ~/.config/github-copilot/xcode, if needed.
2. remove the folder ~/.config/github-copilot/xcode
3. restart / reinstall the GitHub Copilot for Xcode app.

It looks like the Background Permission not granted. Could you uninstall it (you can use the uninstall script https://github.com/github/CopilotForXcode/blob/main/Script/uninstall-app.sh for a full uninstallation) and reinstall the app?

[uo9qsuf]

@lijie-lee yes I did this. But this didn't help.

[lijie-lee]

Hi @uo9qsuf
If the two solutions above does not work, there could be other issues there. Would you mind sharing the log file located at ~/Library/Logs/GitHubCopilot/github-copilot-for-xcode.log?

[uo9qsuf]

@lijie-lee Here is my log from the 0.36.0. The 0.34.0 worksfine. I think it crash by starting the server
