No. An expired .eth name doesn't affect your wallet. Your wallet, the funds in it and your private key don't depend on the name.
A .eth name is a label that points at your wallet. It isn't the wallet itself. Think of a contact in your phone: delete the contact and the number still works; you just have to dial the digits.
What stays the same
Your wallet address: same
0xaddress, same balance, same history.Your other tokens and NFTs: still yours.
Your private key: signs transactions as before.

If the name is in its grace period, anyone can still renew it at the normal price, and nobody else can register it. See Expiry & grace period.
