Hi there,
I’m developing exclusively in Blueprints but am required to temporarily build a Blank project in C++ to compile a plugin, as recommended by the plugin author. Specifically, I “need a project that can include C++ modules and build them”.
When I start a new project with C++ checked (rather than Blueprint) I receive the following error (with the last line displaying repeatedly) and the project is not created:
Setting up bundled DotNet SDK

Some Platforms were skipped due to invalid SDK setup: Mac.
See the log file for detailed information

Can anyone parse the error for what’s going on? Any help would be much appreciated.
I have the latest Xcode installed (26.2) and am running UE 5.6.1 on macOS Tahoe 26.2
