Why rotating objects keeps freezing? (Freeze at 90deg)

As you can see from the photo, I tried all ways possible, and maybe I erased a few more variations. I am trying to rotate a static mesh inside a blueprint, and all that happens is the usual freeze when it’s at 90 degrees. Why is this happening? How can I fix it?

Isn’t this is what you want?

It’s a combination of things ( not looked into it all ):

  1. The tick variant seems to doing some sort of gimbal thing, even though I didn’t think that happened with Add Rotation.

  2. Your timeline code is wrong, this works:

It works! Much appreciated.
