Project crashing while opening

Hello,

I have a problem loading my project, it’s crashing after load screen whatever how I launch it (from epic library, into the folder…)… I’m very confused because I try to learn about UE, but I always have crash or error issues. I can’t work on something without having to do something new the next day…

Here is my crash report :

Assertion failed: LODIndex >= 0 && LODIndex < 8 [File:D:/Build/++UE4/Sync/Engine/Source/Runtime/Engine/Private/StaticMesh.cpp] [Line: 1897]
