Unknown if you have solved this yet but: No Visual C++ installation was found. Please download and install Visual Studio 2022 with C++ components.

Downloading .NET is all well and good but you're missing Visual C++ which is its own components in the Visual Studio Installer.
Open Visual Studio Installer and make sure these two are installed. The former should be the only one that is required but to make absolute sure, do both.
