Unfortunately, I can't say more yet - only on a smartphone.

We need more detailed "Steps to Reproduce".

I tested it again. I think this is because of the built-in server - it is not configured to work multithreaded.
The hot-reload event completely takes up the process, it freezes (waiting for the page to refresh).

On the server with apache2 It works perfectly.

If you use macOS or Linux, you can run it with multi-threads.

PHP_CLI_SERVER_WORKERS=4 php spark serve

I configure vhost. CLI server for fast tests.
