Thank you for reaching out to us through the Community. I am sorry to hear that you are experiencing this issue. I can definitely understand how beneficial it is to be able to edit your work without any interruptions. I will like to look into this for you. What browser are you currently using? Have you also tried switching browsers? Do you have any plug-ins activated as well? When does the error message pop-up? Does it show up after you make a particular action like editing an image block or does it just crash randomly while navigating through the site? If you could provide us with more information by answering these questions, we can try pinpointing the source of the issue! Thank you!
