I'm afraid I did not update my wallet and appear to be on a fork. I purchased coins in 2018/2019 and am on wallet 2.1.2. I can see the block height does not match the explorer.
With this version of wallet, I can see all my coins. When updating to 2.2.0 or 2.2.2, all coins are missing. I've attempted to re-sync a couple times, and all coins are missing.

Is there any way to recover these old coins, or are they gone forever?

Thank you
