Can't drag material onto plane mesh from content browser

I’ve followed a bunch of tutorials and courses where you can drag a material from the content browser onto an object in your level editor and it applies thee material to that object. So i created a new blank level, added a Plane mesh and attempting to drag one of the Starter materials onto it, but all I get is the red “cancel” circle icon. What am I doing wrong? I’m using UE5.1

try 5.0.3 version

I’m using 5.1. Are you suggesting I use an earlier version to address this issue?

I have the same problem, I will try the proposal of a previous version
