How to use crypto to transfer funds internationally?

Background: I'll try to make a long story short; my wife and I owned an apartment overseas in a country she is still a citizen of; we sold the apartment in 2017. We reported and paid US capital gains taxes on the sale on our 2017 IRS 1040.

As a result of this sale, however, the proceeds went into her foreign bank account.

She started making online transfers from her foreign account to our bank account here in the US; her bank's instructions stipulated no more than $10,000 (US value) per transaction and no more than $50,000 per year.

We transferred funds in 2018 and 2019; her bank then became suspicious of these transactions and blocked her from transferring any more funds about two years ago.

Hence, the balance sits in her foreign bank account.

Is there a way to use crypto to transfer the balance; or at least get some of it out?

Any thoughts or suggestions, i.e. a "best practices" way to do it? Please explain as if you were a Ph.D speaking to a high schooler. Thanks.
