I need help with metamask, i have some old erc-20 address(public, lost private key) and i have 400UNI on.

If your wallets are still connected to metamask, you can just export your private key from metamask. That very easy..
Do you still have your wallets connected to Metamask?

That would also be my choice here if you are still connected and have your password:
Just select your address (0x...), go to settings => Account details => Export Private Key
