Freed script error in IE

Ok, I rarely come here for help, but this time I'm really stuck.

I have two pages in Lectora published in v11.3.1.

On page1, I have an action that executes JavaScript: VarXYZ.set("a,b,c,d,e"), i.e. I'm saving a string of letters into Lectora variable.

On page2, I'm trying to get the content of that variable with JavaScript: var data = VarXYZ.getValue(). And this is when IE (all versions from 11 to at least 9) throws this "Can't execute code from a freed script" error in trivantis-cookie.js.

I've never seen it before. The course worked perfectly when published a few months ago in v11.2a.

The course works perfectly in Chrome or Mozilla. The course also works perfectly when I access "" and then go to "". It only fails when I open "" and navigate inside the Title Manager frame.

If I replace my script on Page2 with simple Lectora action "On page show -- Modify variable -- Add to variable -- 123", it also fails. So it's specifically the "getValue()" function that fails when trying to access variable from the last page.

I appreciate for any ideas or directions.
