I never had BSV crap so really do not know how it works however since this is a fork coin of BCH and BCH is a fork or Bitcoin then technically you can recover it if you restore that BSV wallet using a bitcoin wallet software like Electrum unless you have sent them in any exchange.

Download Electrum: https://electrum.org/#download
Verify it before installing: https://bitcoinelectrum.com/how-to-verify-your-electrum-download/
Install.
Have the private key off the BSV address.
Using this private key restore the wallet address in Electrum
You should have access of the Bitcoin.

Note: I think you got wrong board for this topic. It will better go in Bitcoin Technical Support section.
