UE5.2 - Getting this fatal error when playing packaged game. Runs fine with no errors in Editor.

Development Programming & Scripting

I get this error shortly after a widget animation begins playing:

LogWindows: Error: appError called: Assertion failed: RenderBatch.NumIndices > 0 [File:D:\build++UE5\Sync\Engine\Source\Runtime\SlateRHIRenderer\Private\SlateRHIRenderingPolicy.cpp] [Line: 803]

Then my game crashes. I double checked the blueprint and don’t see anything wrong with it. This just started happening. How do I find what is wrong in Line 803?

I am really stumped here. There should be no issues with my widgets. I verified the engine (5.2.1) and get the same error in Standalone or a Packaged game. Zero errors happen and everything is perfect in the editor.

Getting the same error. Has this been resolved at all?
