"TypeError: Cannot read property 'insertBefore' of undefined"

Featured Lock Resolved Bug
Hi all, I have problem with the "Text block" addon in SP Page Builder 3.
When I tried edit the addon I get the next popup message:
"TypeError: Cannot read property 'insertBefore' of undefined"

However, I am able to enter edit mode but when I try to change the "content", as soon as I just click on the "Content" area I'm thrown out of the edit and everything I've worked on is gone.

Please see the attached pictures in the same order of the problem.
