UEFN Error when trying to edit Widget Blueprints or Materials

[paxion]

Summary

When I create a Widget Blueprint (or Materials) and double-click it to open, the editor fails to load. Instead, I get a very long error message (shown in the screenshots), and the editor tab opens completely white, never loads and I also cant tab in.

I’ve already tried verifying the files and reinstalling UEFN, but the issue still occurs.
