I’ve been experiencing crashes as well.
If you’re compiling your code and the engine crashes, it might be a hot-reload problem. Close the engine and from your IDE, perform Clean Solution to remove all the compiled codes, etc… Then, open up your project and the engine will tell you about some missing components. Let it generate everything. If there are any problems there, it most probably will show up in that window.
If that didn’t fix it, see if you have any third-party plugins in your project or not…
