Can not verify and sign with MM

Since 1 week that I signed the new terms and conditions from MM I cannot sign or verify with my MM wallet in any dapp where I was be able one week ago. It’s an old wallet.
It shows me an error about JSON.

I have tried to uninstall and install, seed phrase, export to rabby, reset MM, everything. But it doesn’t work.

I don’t know what else to try.
