Error 1064 Duplicate entry 'ndbcluster-96' for key 'tables.engine'

[Tony Soprano]

I have a production 8.0.33-cluster MySQL Cluster Community Server.
it works fine in the last 6 months until today.
There are 28 working databases in it.

Since today I can't create any table in any dbase because it show always this error:
Error 1064 Duplicate entry 'ndbcluster-96' for key 'tables.engine'

doesn't matter the db name or table name, the errori is always the same.
For sure there is no duplicate vlues cause i used a new empty database with no tables into it.

Any help please cause online i tried anything in the last 12 hrs but nothing works.
I suppose cluster is not sync or an engine problem.
I can not reinstall all by 0 it's a production server.
Waiting your help.
Willing to pay if someone wants to assist me through my share screen or anydesk.
Thanks
