Is Wise bank safe?

With the recent news about Synapse, I am a little on edge with the safety of my money. I am currently living in France for school, and am hoping to immigrate here permanently. All of my savings is in USD, so I need a way to easily and cheaply convert between USD and EUR, and be able to spend EUR locally. After a ton of research, I decided to move almost all of my banking to Wise. They don't offer traditional banking features like in-person branches or checks, but I didn't use those anyway. I can get a local bank number in any of the many countries they support. The savings account APY is insanely high (higher than I have seen from even the best high yield savings accounts. I have a debit card that allows me to spend directly from any one of my bank account currencies, and auto convert to other supported currencies. And the USD account is insured by FDIC passthrough insurance.

In the thread about the Synapse collapse, people were saying that passthrough FDIC insurance doesn't always mean that the customer's money is actually insured. And apparently some fintech services will just lie about what is covered by FDIC insurance. I am not a lawyer, and I have no idea how to validate Wise's claims about passthrough FDIC insurance.

I was recently able to open a France bank account, which was surprisingly difficult. (To open a bank account you need proof of address, like a cell phone or electricity bill. I don't pay for utilities in my school apartment, and to get a cell phone plan I need a bank account. That was fun to try and navigate.) I have these bank accounts currently: my Wise account with US USD, Belgium EUR, and UK GBP, a US Credit Union account, and a French EUR bank account. My US credit union and French banks give a very low or zero APY, so keeping my money in my Wise accounts is preferable for that reason. But I also can't afford to loose all my savings if Wise collapses. My question is this: Is Wise safe enough for general money storage, or should I use it just for converting between currencies and keeping a small amount for spending? If Wise isn't safe, what about another similar product? I have heard of Revolut, but I didn't do much research since Wise seemed better for my use case.
