@canfucius Have you checked if this is related to the "can't load default styles of custom controls" issue (#4414)? More detail and workarounds can be found in that issue and also in CommunityToolkit/WindowsCommunityToolkit#3295.

I used the
<ItemGroup> <FrameworkReference Update="Microsoft.Windows.SDK.NET.Ref" RuntimeFrameworkVersion="10.0.19041.13" /> <FrameworkReference Update="Microsoft.Windows.SDK.NET.Ref" TargetingPackVersion="10.0.19041.13" /> </ItemGroup>

solution and put it both my .csproj files.
