Skinned mesh makes Unity crash on mobile build.

I've tried building a game containing just a skinned mesh in the scene (+ a simple script) and testing it on different phones. On one mobile the game isn't working properly, whenever I activate a skinned mesh and the mesh is visible on the players phone, then the game stutters.

The problem is currently only known on one mobile. I've previously came across this problem in my big project, but tried a fresh project using just one script with a button that enables and disables the mesh I imported.

Whenever I enable the mesh it looks like this: https://i.imgur.com/8m2WZ5S.jpg I'm using the free Unity official's Unity chan model. Here are some more examples of my big project and the problem I'm having: https://imgur.com/a/w7lJGza

I'm currently using the newest version of Unity (older version had the same problem). I'm hoping someone here could help me out.

 

File a bug report with Unity. That's about all you can do.

 

Sorry for the late response, I filed a bug report and got a reply from Unity today. They say the problem is fixed in Unity 2019.1. Thanks for the recommendation to file a report, never done it before.
