Error: Stage failed

Hello all,

I started learning Unreal game development last week. I go based on a tutorial but I strayed off a bit when it came to level design, since I enjoy that more than writing systems. in the past few days I got various issues with Lightmap UVs and overlapping UVs and in general foliage tool was not working at all, crashed the engine and such. I finally get to a point were the light build issues are resolved, so I thought I build a version just to showcase it my friends, and I got the error shown below. Not sure what any of that error means.

Anyone could enlighten me, or tell me what the issues is about? Thanks.

I think I’ve solved it. In case anyone else gets this error: I added a door that was a breakable mesh that required a physics plugin. The functionality worked, but when I launched it, it was not able to package the level with the above failure. After removing the door and disabling the plugin the launch was working again.
