The errors are not the same across releases.
The complete error on F34 is:

I haven’t looked into this thoroughly enough to determine whether it’s
still a problem.
The complete error on F33, F35, and F36 is:

In the current sources for https://src.fedoraproject.org/rpms/usd/,
check pxr/usd/usdShade/shader.h, line 203, paying particular attention
to the comment:
~~~
/// Contructs and returns a UsdShadeConnectableAPI object with
this shader.
///
/// Note that most tasks can be accomplished without explicitly
constructing
/// a UsdShadeConnectable API, since connection-related API such as
/// UsdShadeConnectableAPI::ConnectToSource() are static methods, and
/// UsdShadeShader will auto-convert to a UsdShadeConnectableAPI when
/// passed to functions that want to act generically on a connectable
/// UsdShadeConnectableAPI object.
USDSHADE_API
UsdShadeConnectableAPI ConnectableAPI() const;
~~~
I’m not taking time to track down why the implicit conversion is not
possible here, and I haven’t tried to replicate your COPR in order to
test the following patch, but (despite those caveats) I think that
adding an explicit call to the above method has a pretty good chance of
working:
