Long time to import FBX file to UE4.26

Hi all, I’m using Unreal Engine 4.26 Sequencer to make some cinematics and trying to import FBX file of 91Mb for the Level. It took so much time ( 1 hour) and does not work ( I’m using an IMac 21.5 inch 4K Retina 2019), please advise how to deal with this. By the way, I’ve read a lot of topics on the same problem, please UE4 team fix this asap, many thanks.

91Mb… how many triangles are in that object?

Also, if you’re just doing cinematics there’s some import options you can probably turn off that would speed up import, like auto Lightmap UV’s or auto generate collision
