No smoothing group information was found for this mesh

I’m getting error when export *.fbx from blender to UE5 5.5.1:

No smoothing group information was found for this mesh ‘Cube_001’ in the FBX file. Please make sure to enable the ‘Export Smoothing Groups’ option in the FBX Exporter before exporting the file.

Before this I have worked with UE5 5.0.3 and everything was fine, but then I decided to come to the newer version.

If In Blender I select Smoothing Group when export *.fbx:

… then in UE my model is incorrect:

Hello!
When you exported the fbx with the smoothing groups did you choose the “face” option?
And another question, when importing the UE model are you replacing the existing model or are you importing it as a new one?
