Building Static Mesh render data taking so long

Hello, Im importing to my Unreal Project some tree models for an enviroment. Im import them in the project and everything is fine. But when I drag them to the level, Unreal pops a message:

Loading Package
Building static mesh render data

And it takes a long of time to process, so I dragged 10 meshes to the project to process it so I don´t have to do it one by one and I had been waiting 2 hours for the process to finish, and still is going.

What is unreal doing here and there is a wait to speed it up?

same problem. I imported trees from free content pack from Unreal Store
there are no lags in the editor itself, only when Building Static Mesh render data while project loads.

I installed now Unreal in a SSD, The project folder and Derived Data Cache also assigned for that disk and I got an improvement on the engine. I havent tried with those trees because I moved to another project, so I dont know if that helps with the Building Static Mesh with that tree pack

Yes it is taking a very loooong time. I experienced the same issue even tho I have a really good pc. I don’t know how to fix it. It took 4 hours for me to compile 5 trees in free content pack.
