Dear Forum,
I’m getting a Cook error when trying to package my project.
Error: Assertion failed: Mesh && Mesh->GetRenderData() [File:D:\build++UE5\Sync\Engine\Source\Runtime\Engine\Private\StaticMesh.cpp] [Line: 4425]
Cook-2022.07.03-18.37.50.txt (185.6 KB)
I hope someone can help me out or point me in the right direction.
The way I fix cook errors is to filter out all of the white/yellow warning mrssages and focus on the red ones, often its something simple like a file name being too long or using too many subfolders
Thanks for your reply.
Is there any documentation on the max length of a filename or subfolders?
I would imagine the engine would pick up something as simple as that, and gives the user a proper error message?
Hello TheVolunteerG, I was facing the Same error now.

Did you solve this error?
You are using Unreal 5.0.2 with an Asset made for 5.0.3.
Hello @TheVolunteerG , @TrueFranco and @kpbind .hope you all are ok.
now im facing the exact error when im trying to package the project, found any solution so far?
also, assuming this error is caused by using an asset which was made for the wrong engine version, (as @TrueFranco mentioned) how can i find that asset in the vast ocean of game assets. 
thank you in advance.
here is the error :
