Unreal Engine Issues and Bug Tracker (UE-172407)

Description

Regression: Tested in UE5/Release-5.0, this issue does not occur so regression is yes.

Reproducing this issue has a mixed reproduction rate. I have gotten the editor to crash when scaling the cube up to before even saving the level or opening the World Partition window.

Error Message:

Fatal error: [File:D:\build\++UE5\Sync\Engine\Source\Runtime\Core\Private\GenericPlatform\GenericPlatformMemory.cpp] [Line: 241] 
Ran out of memory allocating 126875245640 bytes with alignment 0. Last error msg: The paging file is too small for this operation to complete..

Steps to Reproduce

Create a new Blank BP Project
Add a Cube to the level
Set the Cube's position to 20000000000, 20000000000, 20000000000
Set the Cube's scale to 1000000000, 1000000000, 1000000000
Save the level
Close and reopen the project
Open the saved level
Open the World Partition window
If it didn't crash, try zooming in and out of the World Partition map

Actual Result: Editor crashes, referencing running out of memory

Expected Result: The World Partition window works properly and no crash occurs while navigating the window.
