Field integrity exception deploying Flows

I'm trying to migrate a Flow from an Org to another one using workbench.

Every deploy done before on fields, objects ecc.. have worked fine, now the only thing left are Flows.

When i try to deploy the package containing this Flow the error i receive is "field integrity exception".

I've removed all static referece to IDs, and i made sure Wide-Org sharing settings are the same between the orgs.

Does anyone have any suggestion?

Thank you.
