I do not understand the issue here. There is some custom SkiaSharp code that is failing because this native Skia library could not be loaded.

This error caused the UI to not display, Because the following code will block if(!_fontManager.PlatformImpl.TryCreateGlyphTypeface(familyName, style, weight, stretch, out glyphTypeface) || !glyphTypeface.FamilyName.Contains(familyName)) **_// look here_** { //Try to find nearest match if possible TryGetNearestMatch(glyphTypefaces, key, out glyphTypeface); }
