Unreal Engine Issues and Bug Tracker (UE-45806)

Description

Adding more than two custom Volume classes to a plugin results in any project that includes that plugin crashing when opening it in the Editor. There does not appear to be a problem with adding three or more custom Volume classes to the project itself.

This is most likely related to [Link Removed].

Steps to Reproduce

Create a new Basic Code project.
Add a new Blank plugin to the project.
Add three custom Volume classes to the plugin (not the project).
Close the Editor.
Build the project in Visual Studio.
Open the project in the Editor.

RESULT:
The Editor crashes while opening the project and shows the following error: Array index out of bounds: 20 from an array of size 20

EXPECTED:
The Editor opens the project successfully.

Callstack

Assertion failed: (Index >= 0) & (Index < ArrayNum) [File:D:\Main-Builds\Stream\Engine\Source\Runtime\Core\Public\Containers/Array.h] [Line: 638] 
Array index out of bounds: 20 from an array of size 20
