Urgent help, all back office disappeared with the last update

The only thing i have done is what you indicate here : https://carbonfields.net/docs/carbon-fields-getting-started/
my fields are in a plugin
For the moment i have rolled back to the previous version.
That’s really annoying, i am using carbon fields in almost all my themes, but i don’t do maintenance for my clients.
It means that i have to go back to all the sites to fix this, once i will have the solution
For the moment i don;t have so much. but i really hope you will not do things like that in the future, it can really be very problematic

So tell me what i can do to fix that and update without problems

Hi,
it’s very strange, i made a copy of the website update again on this on, and everything was ok.
tried on the original site, same problem
i have 3 types of custom fields
options : no pb on this ones
normal cf: no problem
groups of custom fields : these are the ones affected, front end stills ok, but they all disappear from the backend, the add entry is there but i cannot register anything

this is the code which register them :

->show_on_post_type( ‘page’ )
