I updated a Xamarin Forms app to Maui in VS22 targetting .net7 and android 33. We only care about the android version. I used the migration assistant to update the project, then added the files to a new, empty Maui project. It builds successfully now. After the splash screen goes away I get the error below that eventually leads to the error inflating AppBarLayout. I have no idea where the problem is, so I'm not sure what code to post.

Any ideas?

Did you Xamarin.Forms project uses Xamarin.Forms 5.0, and .NET Standard 2.0 or higher? and ensure that it still runs correctly. In addition, you should update the dependencies that your app uses to the latest versions.
The Xamarin forms app was up to date and worked properly before the conversion. All dependencies were updated. They had to be before the project would build.
The failure happens at android.content.res.TypedArray.getDrawableForDensity(TypedArray.java:1007)
In the arrays above, there is no index 13.
Is there a way to test that Maui is properly finding my android resources? They are still in the android resources platform folder with a build action of AndroidResource.

No. This issue appears to be more of a NuGet issue rather than a Maui one, please file this issue to the NuGet GitHub repository
I had the same problem too. After investigating for several days, I found that the following was the problem.
After returning "Thema" of "MainActivity" to the default setting, the problem no longer occurs.
Theme = "@style/Maui.SplashTheme"
It seems like you can't change Thema in MAUI.
