Details

(Whiteboard: sb+) 

Found from SANDBOX_FAILED_LAUNCH_KEYED telemetry.

Chromium sandbox error code is 18 SBOX_ERROR_CREATE_PROCESS, which can only come from [1].

Windows error is 0x00000002 ERROR_FILE_NOT_FOUND.

I can reproduce the same error by renaming firefox.exe and triggering a child launch.
So, cause could be manual deletion/renaming or possibly an issue during update.

I don't have anything actionable to try and fix this, but we should watch this telemetry as we roll out to see how big the problem is.
