Found in 4.24.3 CL#11590370
Reproduced in 4.23.1 CL#9631420, 4.25 Preview 4 CL#12366721, 4.26 CL#12123513

1. Create a Struct (DemoStruct) that has a TimeCode variable.
2. Create a DataTable (DemoTable) from DemoStruct.
3. Open DemoTable.

Result: The engine crashes.

Expected: DemoTable opens as expected.

Assertion failed: (Index >= 0) & (Index < ArrayNum) [Link Removed] [Line: 614]
Array index out of bounds: 0 from an array of size 0
