Does this still happen after you disable the Copilot extension? If yes, please re-enable it and use the Start Extension Bisect command to investigate other causes.

[TheSolly]

Yes, could confirm Copilot is the culprit.

Thank you very much for opening this issue. We are currently investigating Copilot causing crashes and we are consolidating all the findings in https://github.com/microsoft/vscode/issues/176562 We believe this is an out of memory issue, and we can not yet reproduce it on our side. Thus it would be super helpful if you can share reproducible steps (what type of file opened, does this happen when Copilot is suggesting) here https://github.com/microsoft/vscode/issues/176562

Due to the consolidation I am closing this as a duplicate.

If you can reproduce this issue after disabling Copilot do let us know and we can reopen this issue.
