Would the issue occurs in a new project?
You can try to clean your obj and bin floder and update you nuget package. We will wait for your feedback.
New project, I cleaned then rebuilbuit and still have issue. Essentials dosn't even show in the intellisense list
Checkout https://github.com/dotnet/maui/wiki/Migrating-to-RC1 for information on the new namespaces

The Essentials classes are part of MAUI, but not under that name.
RC1 changed the namespaces so that they are focused on specific functionality rather than bundling everything together in a monolithic "Essentials" namespace.
The new namespaces are documented in the Migrating to RC1 page.
