Magento 2 update dont start "rejected by your constraint" - composer-php

Question

I cant update my Magento 2.3.6 Installation. composer update responds with
composer update
Loading composer repositories with package information
Warning from https://repo.packagist.org: You are using an outdated version of Composer. Composer 2 is now available and you should upgrade. See https://getcomposer.org/2
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.
Problem 1
The requested package magento/product-community-edition ^2.4.0 exists as magento/product-community-edition[2.3.6] but these are rejected by your constraint.
I tried several variants ("2.4.2", "^2.4", "~2.4") of demanding 2.4.2 and every variant had the same result. On which constraint does the Error refer?
This is my composer.json
