[Crash] runSofa crashes when using DecimateMesh

[FadiWahbeh]

Description

I created a small scene to test a few compoenent in the CGALPlugin. While testing i founf out that the DecimateMesh component causes crashes. However, the simulation crashes immediately upon launching runSofa whenever this component is uncommented (as you will see in the video).

Since this is my first time using SOFA and creating a scene, it is entirely possible that this is caused by a the wrong configuration from my side, but it's better repporting it.
