[Technical] Private key does not satisfy the curve requirements?

[elonoreblush]

Here's my short story, I used to buy Ethereum on an exchange and send it to a web wallet that no longer exists. I printed out the private key (apparently a good decision) and came back to Ethereum, as Ethereum is continuing to rise. I have a lot of things to pay for and wanted to sell my Ethereum.

I found out that my private key doesn't work and have found out through a local expert that the key is invalid because the private key does not meet the curve requirements?

Is there no way I can get my funds back? That would be more than reassuring after all the research work and despair in the meantime.

Perhaps I don't know the exact wallet you're talking about here so if you can provide us with the exact web wallet you have used them it would be easier to find a solution around it.

I'm not too technical but importation of wallet private keys can be the best way to recover your funds but I don't know what wallet you can import your private keys to, may you can try Metamask if it works.
