Flet-Fehler beim Erstellen einer Windows-Anwendung ⇐ Python

[Anonymous]

Jedes Mal, wenn ich versuche, den Befehl „flet build windows“ im selben Ordner zu verwenden, in dem sich mein main.py-Quellcode befindet, erhalte ich die im Screenshot gezeigte Fehlermeldung.
Ich habe Visual Studio Community bereits mit C++-Abhängigkeiten heruntergeladen.
Wie kann ich das beheben?
Ich habe bereits versucht, Visual Studio Community mit C++ zu deinstallieren und zu installieren Abhängigkeiten ohne Erfolg bei der Lösung des Problems.
Der Fehler:
