I did a similar thing and it's actually pretty easy to recover. Go to albys website and they have a command line tool to recover your balance. You need the seed phrase from when you set up albyhub. It will force close your lightning channels and return everything to your on chain balance. You can create a new alby hub and send your sats over. If you have another wallet that lets you transfer between on chain and lightning (like strike) you can buy a lightning channel, which is cheaper than having a big enough on chain balance to open your own.
