Can't edit forms any more

We are using: PHP Versions 8.0
WP Version - 5.71
Chronoforms Version - 7.0.7
​
We recently updated PHP and WordPress. I can no longer edit any forms - the GUI is gone. I've attached a screenshot.
​
The GUI is fine when opening up Chronoforms, but clicking on any form to edit it give s what you see in the screenshot.

Hi dnigra,
​
No screenshot attached but my guess is that this is a result of using PHP 8 - I don't think that Max has yet been able to update CF to work with the new version.

Thank you, that was it. Rolled back to PHP 7 and we are back in business. Thank you again.
