GraphQL (SendQueryAsync) deadlocked when executing from Maui ViewModel initializer

GraphQL query runs just fine when I run it in a C# console app. Using the exact same GraphQL Client, similar code and properties it hangs when I try to run it from a ViewModel initializer in Maui. An exception is thrown: "System.Reflection.TargetInvocationException: ‘Exception has been thrown by the target of an invocation.’"

If I manually build the list it works, but I want to build the list from a query.
