It looks simmilar to #48436 , but it started happening to every code completion and I have absolutely no clue how it happened.

It happened after I moved(using shift+arrow keys to select, tab to indent and alt+arrow keys to move down)  the three dicts in the picture to within the function and added the dict 4.

### Steps to reproduce

Here's roughly what I did 
(might be slightly inaccurate, I was basically messing around to try and see the scope of $77725 when it happened)

1) create an empty script
2) declare a couple of dictionaries
3) declare a function
4) try out code completion within the function
5) create a lambda within the function and try 4) again
6) move the dictionaries' declaration within the function using keyboard shortcuts and try 4)
