Unreal crashes when Importing FBX

SO My Editor will crash when I try im port my FBX, It is a really big FBX (Its the entire grotto + some terrain from fortnite) and I really need it to stop crashing If somebody knows some way to make it not crash, Even like make it freeze and slowly import the POI, The File is 60.2 MB btw

Btw Im on uefn but I've used unreal and they arent that different
