Unreal crashes when trying to use Substance live conection with Datasmith imported geometry

Hello!
I am using Datasmith mainly because is the only way to import assets from 3dsMax and maintening their original axis. (Any other way is welcomed)

After importing a Datasmith file into Unreal i go to an imported geometry asset, right click and choose : “Send to Substance Painter”
Unreal crashes giving me the following information:

Access violation - code c0000005 (first/second chance not available)
