Hello, yesterday I edited the main map of my game, and everything seemed normal; I didn’t encounter any errors. However, the following day, I realized that I couldn’t access my main map. When I attempt to open the map by double-clicking, it crashes. I haven’t found any similar error topics on the internet, and I’ve been unable to solve the problem for a day. Is there a solution for this? The error is as follows:
Assertion failed: SerializedElementSize == 0 || SerializedElementSize == ElementSize [File:D:\build++UE5\Sync\Engine\Source\Runtime\Core\Public\Containers\Array.h] [Line: 1284] Unexpected array element size. Expected 4, Got: -1758990265. Package can be corrupt or the array template type changed.
