VS Code Insiders keeps crashing

Type: Performance Issue

Using GitHub Copilot and about 3 minutes into my workflow VS Code hangs and I have to close or re-open the app. As soon as the agent starts working on on anything semi-intensive.

VS Code version: Code - Insiders 1.115.0-insider (Universal) (3d70aab9a4ed407832e43584ac7a661be08e2d74, 2026-04-03T09:58:58-07:00)
OS version: Darwin arm64 25.3.0
