Going by your sample project and your csproj, I believe that error is correct: You didn't embed a font. OpenSans- Semibold.ttf is an included font inside the Resources/Fonts folder and is not embedded. You have no embedded font files in your csproj. So, you're referencing a non-existent file.

If you include an EmbeddedResource of a font, and use the correct file name and font name, it should work.

You may want to refer to the documentation.

I have verified the sample, and I have set the Build Action for the font file as 'Embedded Resource' and ensured that it is added with the correct file name. However, I am still encountering the problem

any progress now？

As far as I can tell, there's no bug. As I wrote above, OpenSans- Semibold.ttf is not embedded, it's part of theResources/Fonts directory in a default MAUI template app. Trying to access it as an embedded font will cause an exception, since it's not embedded. If you actually embed a font, as the documentation shows and my screenshot shows by updating that provided sample to include a real embedded font, it should work fine. If it's not working for you, you probably didn't configure it correctly.

I would file a new issue if you're having a problem with it, preferably with an example showing what you're trying to do.

Thank you，just solved this problem by clear previous data and rebuild .During testing,the font could be found in the apk,but exceptions keep appearing when the code is run.A little strange.
