Hi,
I have recently switched my project from 4.15 to 4.16. After that, every time I try to open mesh editor the engine will crash. Here are the logs:

I have tried Removing project’s DerivedDataCache and deleting /binaries /Intermidiate /Saved folders and rebuild the project, but editor still crash every single time. I also tried creating a ThirdPersonExample project in 4.15 then switch to 4.16 and it works totally fine. I have no idea what’s so special about my project that make the editor crashs so unswervingly like it’s part of the engine features. Please help.
Thanks in advance.
