Answering in Edge produce a white screen crash

Hi
You have created a great WP plugin!!
However, I found a problem when the user is trying to answer a question using Edge (Firefox also was reported).
When the user tries to answer, just by clicking on the text editor for answering will produce initially loading and then redirection to a blank white screen.
Any idea how to fix this?
Initial screen:

I appreciate your help.
Thank you.
