So the question is how to properly CONVERT to nanite meshes  
its look some sort of nanite settings make this problem, but cant pinpoint the problem. even im tried version 5.3. different PCs and etc.  
previously i have imported 10k+ part in UE5 without any problem… ( few months back on the 5.3. version

So for everyone if get in similar situation get help from fiend Libor

1. check if youi see NANITE TRIANGLES
2. go to LIT / UNLIT and scrol down for NANITE VISUALISATION / TRIANGLES  
3.if you dont see the colored triangles its mean NANITE is not working even its ENABLED

you need to go to the proejct settings file /Config/DefaultEngine.ini  
and look for  
r.ForwardShading=True

set it to FALSE
