Not all exceptions are caught when generating the site

Problem/Motivation

When generating the static site on a Drupal site, not all errors are caught. TypeError extends Throwable and not Exception, so the static site generation breaks with

The website encountered an unexpected error. Please try again later.

TypeError: Symfony\Component\HttpFoundation\InputBag::get(): Argument #1 ($key) must be of type string, null given, called in /var/www/html/web/core/lib/Drupal/Core/Routing/RouteMatch.php on line 127 in Symfony\Component\HttpFoundation\InputBag->get() (line 28 of /var/www/html/vendor/symfony/http-foundation/InputBag.php).

Steps to reproduce

In my site, having "Custom Menu Links (menu_link_content)" core module enabled made it fail. That module has an entity without bundle and the if ($path && $url->access()) { line in tome_static...RoutePathSubscriber.php throws the TypeError as seen above.

Proposed resolution

Change \Exception for \Throwable when trying to catch possible exceptions.
