Twig crashes when baking models or other things - cakephp

Question

I have installed a new cakephp-4 (4.2.x) app skeleton on a Windows machine under xampp (PHP8).
when I try to bake something, whether everything (all), models or just controllers, Twig crashes with an exception.
Exception: Class "templates" not found
In [C:\xampp\htdocs\...\vendor\twig\twig\src\Environment.php(359) : eval()'d code, line 16]

the exception thrown inside an eval call. If i dump the eval()-code, this is the result:
1: <?php

17: {
18: private $source;
19: private $macros = [];
Line 16 is the problem (there is no class templates).
I don't know enough about twig to look for the fault; Googling didn't help.
Does anyone have any idea what could be the cause of the error?
