Script not working on an imported asset

Hi, I'm a new unity and c# developer. I am currently working on a simple game where a player controls a rocket sprite through obstacles. I made a very simple script to make the obstacles rotate. The obstacles I am using are from a free imported asset pack from the asset store. However when I apply the script to the imported obstacles it does not rotate. I tried applying the same script to a regular gameobject on unity and it worked like a charm. For some odd reason it doesn't work when I apply it to the imported assets. Does anyone know why it isn't working?

 

Some potential reasons may be:

• The asset object may have a script attached which handles movement, overwriting your changes
• The asset object may have a rigidbody, but blocked rotations/movement on some or all axis
• In some rare cases the mesh of the object is entirely handled through a shader, which doesnt seem likely for an obstacle tho

Pretty sure it's the rigidbody component with a blocked rotation and movement, since that would make sense for an obstacle.
