My .net MAUI program is getting the same error after upgrading VS preview from Version 17.4.0 Preview 1.0 to Version 17.4.0 Preview 2.1. It's working at .NET 6.0.486 and Version 17.4.0 Preview 1.0. I manually installed the SDK 31. All the dependency error are gone. Now I am getting below error only in release mode. (An item with the same key has already been added).

I am searching the error message online. I found this post: https://stackoverflow.com/questions/73183482/an-item-with-the-same-key-has-already-been-added-maui-c-sharp What is the correct way to fix this? Is this a bug from VS preview?

Currently having the same issue, I'm running the latest version of visual studio 2022 preview and can't even load up the default .NETmaui sample app.

When compiling on the windows machine

when going to (Tools > Android > Android SDK Manager) and updating I recieve this error
