is there a way to get these segwit bech32 addresses converted into regular addresses
to check them out on blockchain.info and use them for fork claimings?
have you tried querying your bech32 address on BTCP blockchain explorer?
forked chain usually have a built-in address conversion to query and search it
if it returns a result then you can try finding out a way to claim it
if it gives error invalid address then most likely you won't have a chance to claim it
