I started getting this error on every page I open in my project. I’m thinking it is a problem when a share resource file as the message does not point to a specific page. The project runs on the client but any work in designer keeps throwing errors. Anticipating worse things to come!! ☹

In Session Events → Page Startup, you have code that isn’t compiling.
