I downloaded the ​​Electric Dreams Environment sample project​ ​ from the ​​fab website​ ​. I then attempted to open this project using ​​UE 5.6 (Official Release)​ ​. The sample project launched correctly and ​​automatically loaded the StartUp map​ ​. However, when I tried to open another map (​​ElectricDreams_Env​ ​), ​​UE 5.6 immediately crashed​ ​. The ​​crash log is as follows​ ​:

Assertion failed: (Index >= 0) & (Index < ArrayNum) [File:D:\build++UE5\Sync\Engine\Source\Runtime\Core\Public\Containers\Array.h] [Line: 1067]
Array index out of bounds: 24581 into an array of size 1954

Based on the crash log, it appears that an ​​access violation occurred while loading a static mesh​ ​. This was likely caused by ​​asset corruption or incompatibility​ ​.
Has anyone encountered similar issues? Are there other potential solutions to try?
