dns: the old registrar had DNSSEC enabled and, after the transfer, the new registrar does not support it. Now the site does not load

I made a domain transfer with DNSSEC enabled to an operator that is not compatible with DNSSEC. The first operator has no option to disable DNSSEC, and anyway I did not think about it. And now I have a problem: the transfer was made on Thursday and the domain until today is not visible anywhere in the world (including Google DNS). Could it be due to DNSSEC?
Is there any chance of completing the spread in this situation?
