If I get an exception while programming, the first thing that I do is search Google/Bing for the exception. 99.99% of the times, I get a solution. I did the same for your question and this was the very first result - Failed to load viewstate ? Typical problem, with an obvious solution[^]
More here - Google search - Failed to Load ViewState[^].

I hope that idea of Googling will save you (and us) a lot of time in the future! :thumbsup:
