Cant Import FBX

hi, ive been modelling individual buildings for a game for about 3 weeks now and finished them now, when importing to unreal after selecting the .fbx i get the following error “Failed to import ‘D:/3DWork/UE4_FPS/Architecture/Building_Laboratory.fbx’. Failed to create asset ‘/Game/Building_Laboratory.fbx’. Please see Output for details.”

and the log message reads,
“Can’t detect import type. No mesh is found or animation track.”
im using UE4.17

Well, it seems like your fbx file is corrupted. How was it created? Which tool did you use to export it?
