I think another issue would be mining to the hardware wallet. Because I mine zcash and I think the issue here is the ledger live not able to synchronize to the mining transactions. I think this forced itself to wipe out. Because on the ledger USB I have has not wiped out but the ledger live wiped out
Problem with Zcash mining and HW is fully explained in second post, and you should not try to use Nano S for that purpose for now. Solution is to use some other wallet for receiving mining transaction and then send larger amounts of Zcash to Ledger Nano S.
You say that your Ledger device is up to date with firmware and you use latest Ledger Live, but be sure that you use latest Zcash app. Remove all app from your Ledger Live and then install first Bitcoin app and then Zcash app. I am not sure is this can help to see your Zcash balance in Ledger Live, but it is worth to try.
