Hey, thanks for the report. Code -2147483645 aka 0x80000003 Windows STATUS_BREAKPOINT is a known crash at the Chromium sandbox level, not a Cursor bug. It usually shows up after a Windows Update when GPU drivers change or security software starts handling sandboxed processes differently.

Try this in order:

  1. Update your GPU drivers from the vendor site NVIDIA AMD Intel and reboot. This fixes it in most cases.

  2. Clear the GPU cache. Delete these folders:

    • %APPDATA%\Cursor\GPUCache
    • %LOCALAPPDATA%\Cursor\GPUCache

  3. Check your antivirus or EDR CrowdStrike Bitdefender Webroot Sophos etc. After updates they can start blocking the Chromium sandbox. Temporarily turn off real time protection and try launching Cursor. If that works add Cursor to exclusions.

  4. Temporary workaround. Right click the Cursor shortcut, go to Properties, and in Target add --disable-chromium-sandbox at the end. Running without the sandbox is less isolated, but it’s safe for normal use.

If any of this works or if nothing helps, let me know. Also share your Cursor version and your exact Windows version so we can narrow it down.
