CPU access error problem?

Hey guys

I set up the Static Mesh Location to spawn particles to the Static Mesh vertex location information, and connected the BP to reference the parent Static Mesh.
However, I had a problem with not getting the vertex location information of the Static Mesh, so I opened Niagara to check and it said CPU access error, so I clicked Fix Now and saved it.
After saving, when I turn off and on the editor, I have that problem again and I can’t find the location information, but even if I search on Google, I can’t find a solution, so I’m leaving an inquiry post.
If you have any experience in solving this problem, please reply!

Had the same issue and the solution was to add a user parameter to read the skeletal mesh, ignore the CPU access error, add the new input to the mesh module, and in the emitter properties use GPU to render as the SimTarget.
