Crash when importing a skeletal mesh

UE4 Editor is crashing when i am trying to import a skeletal mesh. Mesh in question is a cloth for my char so when importing i am assiging my char skeleton as skeleton.
It then crashes with Array index out of range error. I am on 4.24.3. However same mesh works fine when i import it on 4.22.3. I do have materials assigned on mesh. But it still crashes
Is this a bug??
Anyway to get around it
