Please help me. Mr. Kamiya's study group investment scam/no contact.

Like others, I opened an account with Kaerm IM, which was recommended by Mr. Kamiya, and made repeated investments. When I tried to withdraw money, I was suspected of money laundering and was told that I had to pay a fee to withdraw money. I can't withdraw money. I have consulted with the police and a lawyer, but it is a difficult situation because I have an overseas account. Please lend me your help. I applied last time, but I have not been able to contact them. I am really in trouble. I paid 6.8 million yen for the transaction and as a security deposit.
