Error: $ctx not defined

What are you trying to do? (please be as specific as possible and include relevant screenshots, code snippets, and reproduction steps)

I was adding a page variable that would contain an array of objects filtered from a query. I have done this for a number of variables on this page before.

Upon update, I got the following:

In fact no dynamic data seems to be available on queries:

Note: 1. Other pages in the project do not have this issue. 2. This page works perfectly well in Preview mode

What have you tried so far? (please link relevant docs and other forum posts)
I tried duplicating the page but it did nothing

Relevant links:

UPDATE: I have about 5 variables whose initial values are derived from filtered query results. If I drop the initial value calculation for any single one of them, the studio starts working again as expected.

UPDATE2: pretty much any extra change (e.g. moving a dialogue element into the header) can trigger this error. It looks and feels like I have reached the maximum complexity the studio can support. Is this true? This kinda blocks my development efforts would appreciate some help.

Hey @alexander_eliseev,

I am investigating the issue and will reply back here when I find something.
