Crash at runtime when Retainerbox scale is set to 0.
The call stack indicates that the size of RenderTarget2D is set to 0. Attached repro project sets the scale of the RetainerBox that wraps the Image to 0 in the constructor.
A workaround is to change the following log verbosity.
UE_LOG(LogUMG, Error, TEXT("The requested size for SRetainerWidget is 0. W:%i H:%i"), RenderTargetWidth, RenderTargetHeight);
This will cause crashes even with relative changes, such as changing the scale of the panel that wraps the Retainerbox. It did not occur crash in 4.25.
