Avia layout builder – Text Bloc – Text Missing

Hi,
Can’t tie this back to an exact update however my pages have become corrupt. Where I have a avia layout builder text block the existing text is not visiable when editing the element. In the element preview there is a prompt that says the following “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.”

If I select the Text rather than the visual view then I get this scambled HTML.

The page is a contact us page. It has a google map with GPS marker for our business. It has a text block with address and contact numbers and lastly, it has a contact form. Every other page that uses a text block also has the same issues. Above the avia layout builder is the classic editor which I prefer not to use or see. I am not able to apply any changes via the classic editor. I have tried recreating the page, removing blocks etc to no avail. Please assist urgently.
