New project install: Allowed memory size of 2147483648 bytes exhausted (tried to allocate 421768368 bytes)

I am new to Laravel, I have installed PHP and Laravel in a Docker container.

From installation tutorials, I was expecting a Laravel Homepage, however I am getting a memory error.

For avoidance of doubt, I have not adjusted any code. I've taken the PHP right up to 3GB, with the same result.

Symfony \ Component \ ErrorHandler \ Error \ FatalError Allowed memory size of 2147483648 bytes exhausted (tried to allocate 421768368 bytes)

PHP 8.2.7, Laravel 10.24.0

I'm running it using an Apache Bullseye image.

If I run a core PHP file from the server, and utilise a high memory usage test, it works fine. Once the index.php file gets to:

$response = $kernel->handle( $request = Request::capture() )->send(); $kernel->terminate($request, $response);

It breaks. Seems there is likely a loop somewhere, but I'm not clear on how a fresh install project with no adjusted code can create that?

Any ideas very welcome?
