Just upgraded from 4.8 to 4.9 to 5.0 then to 5.0.0.1. I was able to login to the 4.9 upgrade to verify everything was ok. THen after upgrade to 5.0, as soon as I click on Login I loose the contents of my modules and I get the following error message:

  A critical error has occurred.
Exception has been thrown by the target of an invocation.

I click on Login again and I get the Login module. I enter my credentials and then I get the contents back but I get the following message in my COntentPane:

A critical error has occurred.
Failed to load view_state. The control tree into which view_state is being loaded must match the control tree that was used to save view_state during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.

Furthermore, it appears I'm not logged in because I don't have any admin menus and the Login link still says Login.

Any ideas?

I have the same problem.  I click login a second time an it works and then throws the error on the homepage.  Not a solution but a workaround for now.
