First of all, be sure that your Nano device and its apps are up to date in terms of firmware and updates respectively.
If that is not working, clear your cache and delete and re-create your Ethereum account.
If even that doesn’t fix it, then maybe you should delete and re-install your Ledger Live.
But, don’t be scared. Even if you can’t fix this problem, you could connect your Ledger with Metamask. Then you will be able to see and transact with your ERC-20 tokens through it. Don’t rely only on your Ledger Live account.
P.S.1. If you import your address in Etherscan you can see your ERC-20 tokens (you have MKR, MATIC, LINK, and UNI) so this should be a relief for you.
P.S.2. Don’t answer any DMs. They are scammers. NEVER give your 24 word recovery phrase to anyone.
P.S.3. None of the above is financial advise of any kind. Good luck!
