Unreal Engine 5: C++ bug?

Hello, I'm encountering an error in Unreal Engine 5.1. Does anyone know how to fix this?

 Error: An error occurred while trying to generate project files. Running C:/Program Files/Epic Games/UE_5.1/Engine/Build/BatchFiles/Build.bat -projectfiles -project="C:/Users/--------/Documents/Unreal Projects/MyProject4/MyProject4.uproject" -game -rocket -progress Running UnrealBuildTool: dotnet "..\..\Engine\Binaries\DotNET\UnrealBuildTool\UnrealBuildTool.dll" -projectfiles -project="C:/Users/--------/Documents/Unreal Projects/MyProject4/MyProject4.uproject" -game -rocket -progress Der Befehl "dotnet" ist entweder falsch geschrieben oder konnte nicht gefunden werden.

LG in advance.
