Textures not displaying after 4.24 update

I have some icons used in widgets. After updating from 4.23.1 to 4.24.1 on Friday, these icons are showing up as all white. The textures are in the project and open up ok. But they don’t show up in the widgets. Blueprint calls to set the widget images with textures don’t work.

Anyone know what could cause this or how to fix it? I have another sample project downloaded from the internet with similar buttons, and it has the same problem.

I have the same problem after updating from 4.25 to 4.5.1
