Whenever I try to launch my game on a device, it will immediately crash.
I have narrowed down the cause to a simple static mesh that I am using. If I have the mesh imported, but not used the game will launch fine, however if I place the mesh on my level, or if I use it as the mesh for a spline and try to deploy, the game will crash on launch.
The game works fine for in editor testing, it only crashes on the android device. The mesh is a simple 3 sided cylinder with about 5 segments, it is designed to be used as the mesh for a spline.
I got the error log from ADM, and it says something about a nav mesh… I’m not using any sort of navigation in my game but I also tried adding collision to the mesh and a navigation volume to the map with no luck.
