The problem somehow lied in the fixtures

async function deployToken() {
    const Token = await ethers.getContractFactory("Token");
    const token = await Token.deploy();
    await token.waitForDeployment();
    const tokenAddr = await token.getAddress();
    return { token, tokenAddr };
  }

async function deployFundedToken() {
    const Token = await ethers.getContractFactory("Token");
    const token = await Token.deploy();
    await token.waitForDeployment();
    const tokenAddr = await token.getAddress();
    const oneEth = ethers.parseEther("1");
    await setBalance(tokenAddr, oneEth);
    return { token, tokenAddr };
  }

I had these two fixtures. When I deleted the funded one and just started to fund when I needed to the balanceOf func and all the other ones became callable. Does anyone know why though?
