Are you unable to open your form inside of From Builder or inside of browser?
I have checked form https://form.jotformeu.com/60974999883382 that was last modified on your account and I was able to open it inside of Form Builder and I was able to open it in new browser tab.
It was probably temporarily issue. If you are still unable to open your form, please explain in more details where the new form will not open. Also if possible please provide us a screenshot.
Let us know if you need further assistance.
