Monolog Fehler in app

Guten Tag liebe Community,

ich habe mir ein Contao4 lokal mit xampp installiert, um dort meine Erweiterungen zu programmieren.
Durch ein Problem mit meiner letzten Installation (hatte mir da etwas zerschossen), habe ich ein neues Contao4 installiert.

Dabei sprang mir auf der Startseite ein Fehler in der app_dev.php entgegen:

Code:

Dieser trat bei der anderen Installation nicht auf.

Ich habe diesen Fehler auch schon mal auf einem Contao4, welches auf einem Webserver (Hoster - DF) lief, gesehen.
Im Frontend und Backend sind keine Fehler, nur in der app_dev.php gibt es diese Warnings.
Es ist derzeit eine völlig blanke Contao4 Installation, welche lokal unter php7.4 läuft.

Kennt jemand diesen Fehler und weiß, wie ich ihn beheben könnte?

Mit freundlichen Grüßen

xCerberus.
