Something wrong with my "Avia layout builder" text block editor.

Hello. Ever since the last theme update I have difficulties editing or writing new text in my editor in Enfold. I use the Avia layout builder and normally when I write text I choose the text block under content elements and write my text in the visuel editor. But now when I open the box it’s all white with a lot of red lines, like the code is hidden in the box. In the box next to the editor it states “It seems you are currently adding some HTML markup or other special characters. Once all HTML tags are closed the preview will be available again. If this message persists please check your input for special characters and try to remove them.”

What am I doing wrong and how do i fix it, so I can edit my post in the visual editor
Im running the latest WordPress and Enfold theme
