Hello, I’m having an error when opening Ignition perspective. I was trying to export a project from one designer and import it into another, but when it doesn’t properly copy over the views or the named queries. In fact, the views folder is missing entirely from perspective. Please see the logs below.

You should get in contact with support. Something is going critically wrong during designer startup; it’s hard to pinpoint exactly the root cause from the isolated stacktrace.
