Hello, why dont you use the website Copay has to recover the Bitcoin Cash? https://bitpay.github.io/copay-recovery/
They basically scan your funds in BitcoinCash and let you send them to another wallet.

They recommend you to create and do a backup of a new wallet and then follow the procedure, that is because you will have to introduce your wallet backup file or word into the website tool.

give it a try and then post the results.

good luck
