Browser console error related to form loading twice

Hello,

I am getting below error in browser console
[attachment=3]error.png[/attachment]
when I try to open the form i.e. if I have one parent form which is currently open and I have a list inside the parent form, on click one of the items in the list I open a new form in the next tab but it throws the above error and instead opens the blank form. This was never the issue earlier and nothing had been change, I am still trying to debug the issue but unfortunately haven’t found anything yet.

Can this be the reason form doesn’t open. Because my parent form contains the list form inside and from the list form I try to open the same list form in another tab.
Please suggest if possible.
