Hello. I’m trying to create a blank C++ project but it throws an error. I installed VS Code and Rider and UE5 can see them and switch to the IDE if I’m trying to open a new C++ file from it. But even if I open the UE project in Rider, it throws Can’t compile because some root classes missing. Here in the log I see something isn’t available - what should be done to fix this issue?

I installed UE5 via 3rd party “Unreal Engine Asset manager” and use OpenSUSE TW with modern libs.
Another project with blueprints. Added a C++ file. Error from Rider:
