Engine crash when assigning Apex cloth to material

I am encountering a crash every time I am trying to assign my .apx file to a material of the skeletal mesh. I have a feeling there is something wrong with my apx file, but nonetheless it shouldn’t crash at least.
Here is the crash log. I don’t have a lot of knowledge of Apex yet, and this was supposed to be a simple test, so here I am asking for help from the overlords.

I seem to have found the problem. The fbx was imported with cm units. When exporting the apx file, it has its own option to set units, which was set to metre. The crash disappeared after i exported the apx in cm units.
