What's Wrong?

Randomly executing claude throws an error:

This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). The promise rejected with the reason:
RuntimeError: access to a null reference (evaluating 'P$.apply(null,iI)')

What Should Happen?

The application should open and run.
