I would be great if you can help me, all of my process and methods are running in threads and are async

@NeidennX

I am not certain that that error message is the true reason that your app is not launching.

You might need to provide a test project that reproduces the issue to be able to debug what is going on.

Feel free to open a free Xamarin support case where a Xamarin support engineer can help you one on one and yu can provide code privately and securely.

Same problem here but only once when I click my custom Renderer for Android. Reproducing will prove to very difficult. I've got 2 solutions. In the one (the smaller that I could send you) it's working perfectly. In the other (the bigger project) It's not. I can pinpoint this to be on a custom control I'm writing and debugging right now. I've created a question on StackOverflow here. If you go there. I've already concluded it is not in the Slider class

This message is misleading. It just happened to coincide with my click on the Control I'm debugging. So forget what I said.
