Did you make the trees with Blender3D? If so, consider this:

Blender3D objects used as trees / detail in Unity3D terrain (See the second half of this response)

Terrain Editor Adds The Trees in Wrong Rotation (Custom Trees Made With Blender)

This might be because your scene includes the default camera and lights. Unity started importing those with its default Blender import script starting sometime in Unity2019 and it will break a lot of prefabs. You can either a) remove the Camera and Light and everything except the LOD group objects (properly named), or you can modify the Blender import script embedded in Unity. This means you would need to re-modify it every time you switched to a new version of Unity, but I was …

ALSO, just some more random tidbits on Blender3D and Unity3D:

From Blender to Unity problem

Often distortions can come as a result of modifiers and/or scales existing through your transform hierarchy. In Object mode in Blender, always have your rotations set as (0,0,0) and your scales set as (1,1,1) otherwise you will have issues. You can apply those transforms in Blender. Unity runs this script to import your Blender files via transient FBX export: ./Hub/Editor/2020.1.5f1/Unity.app/Contents/Tools/Unity-BlenderToFBX.py ./Hub/Editor/2020.2.1f1/Unity.app/Contents/Tools/Unity-BlenderT…

The script that Unity uses:

./Hub/Editor/2020.2.1f1/Unity.app/Contents/Tools/Unity-BlenderToFBX.py

All my mesh folder content is gone

There are no "mesh files" from a standard Blender import. Unity imports a Blender file as a series of different assets depending on what you put into it in the first place: GameObject, MeshRenderers, Meshes, Materials, etc. All Unity does when it imports a blender file is call the Unity-BlenderToFBX.py script (located in your installation of Unity) and imports stuff. If you recently upgraded Unity, around Unity2019 or so, they changed what they imported, so it will reshape EVERYTHING in your…
