Hang tight while we set up your new Blitz app!

### Please include below any other applicable logs and screenshots that show your problem:

_No response_

Reproduce the failure with the listed `blitz new` choices and inspect `AppGenerator.updateForms` in `@blitzjs/generator`; the trace points to the missing `_forms/hookform/Form.js` source. Confirm the intended template layout and make sure generating a full JavaScript app with React Hook Form completes without the assertion.
