Hey, this is a known crash with error code -1073741819. A few things to try:

  1. Disable hardware acceleration: add "disable-hardware-acceleration": true to argv.json. Open it via Ctrl+Shift+P → “Preferences: Configure Runtime Arguments”. Save and restart Cursor.

  2. Update your GPU drivers. Outdated or buggy video drivers often cause this exact crash.

  3. Check for an OTEL memory leak: Ctrl+Shift+P → Developer: Toggle Developer Tools → Console. If you see [otel.error] or OTLPExporterError, that is a known memory leak that can lead to crashes.

  4. Rule out extensions: try launching with cursor --disable-extensions and see if it still crashes.

  5. Watch memory usage: Ctrl+Shift+P → Developer: Open Process Explorer. If the renderer gets close to 3,5 GB, that is likely the trigger.
