Problem: package rpm-build-4.19.91-1.fc40.x86_64 requires rpm = 4.19.91-1.fc40, but none of the providers can be installed
  - package rpm-4.19.91-1.fc40.x86_64 conflicts with redhat-rpm-config < 290-1 provided by redhat-rpm-config-289-1.fc40.noarch

Issue: The build requires rpm-build-4.19.91-1.fc40.x86_64
This package requires rpm = 4.19.91-1.fc40
However, rpm-4.19.91-1.fc40.x86_64 conflicts with redhat-rpm-config < 290-1
The build environment has redhat-rpm-config-289-1.fc40.noarch installed
Resolution: Add an explicit dependency on the newer redhat-rpm-config into the spec file:
BuildRequires: redhat-rpm-config >= 290-1
