[Solved] Visform fields settings are broken

Good morning, I have 4 Visforms working for years.
Now I can't access to the fields settings and Joomla give me an error page.
I can see all my fields ad usual but when I click on the specific field it seems broken.

I have the last Visform version for Joomla! 3 and I'm using Joomla! 3.10.9

Can someone help?
Thank you very much

Hi Aicha,
I've installed the last versione of both..
I downloaded again both from the website and reistalled it on my website but the problem is still here..

Thank you very much

Hi,
could you please provide the version numbers?

There is no known error and all known errors are fixed.
Therefore I need as much exact information as possible.
What did you do, before the error occurred the first time. (Install something new, Update something...)

Aicha

Hi,
here you can see all the versions informations:  ibb.co/SBwXdDB

I uploaded only Joomla! and some plugins (firewall, backup service etc), anything else.
I have conditional fields I can't reach anymore. I can see all the fields in my backend but when I click on a specific field I have the error.

Thank you very much

Hi,
thanks.
Versions are fine.

Could you please provide that call stack for the error.

In the global configuration set the "Debug System" (Tab "System")  to "yes" and the "Error Report Level"  (Tab "Server" to "Maximum"
