At first I had issues with connecting to the network - running a bat file helped me. After that, literally the same thing happened to me like to OP, it can’t be a coincidence. Used my recovery phrase to restore my wallet, after that it showed me balance of 0 ADA. Also used cardanoexplorer and it shows proper balance.
EDIT:
Fixed the problem. Had to delete whole %APPDATA%\Daedalus catalog and reinstall the program. This thing happens when for some reason you close the app during wallet restoration.Deleting only Wallet-1.0 does not solve the issue, everything has to removed.
EDIT 2:
I just wanted to say that confusing thing is that if your turn on Daedalus after closing it while restoring, your wallet is added to the list anyway. Deleting Wallet-1.0 removes it, and if you try to restore your wallet once more, it gets successfully added almost instantly without fixing your account balance
