Is it possible to uncover the plaintext if IV is used twice but the key is different?

I am currently working on a cryptography challenge. The program uses AES-GCM to encrypt and decrypt strings.

Let's say I have the following:

IV which is reused
only 1 cipher text
authentication tag
AAD data

Is it possible to uncover the plaintext even if I don't have the key? I've read somewhere that IV reuse is bad but is this true even if the key is different?
