Hello,

## Before I upgraded my project to UE5 from UE4.27, I was able to package without issue. Now i am getting:

## “PackagingResults: Error: appError called: Assertion failed: Mesh && Mesh-\>GetRenderData() [File:D:\build++UE5\Sync\Engine\Source\Runtime\Engine\Private\StaticMesh.cpp] [Line: 4828] PackagingResults: Error: begin: stack for UAT PackagingResults: Error: === Critical error: === PackagingResults: Error: Assertion failed: Mesh && Mesh-\>GetRenderData() [File:D:\build++UE5\Sync\Engine\Source\Runtime\Engine\Private\StaticMesh.cpp] [Line: 4828]”

There doesn’t appear to be any help with this issue as of yet. It’s a little frustrating not being able to troubleshoot this.

Any help would be appreciated. 😄
