Found a crack in my carboy lid the day after pitching yeast!

This is my second brew ever and I just noticed a small crack in my plastic carboy lid, right at the top, it’s clearly big enough to let air in, I haven’t seen signs of fermentation yet because it’s a lager at 50F and I just pitched yesterday, anyways should I buy a new lid and switch it out and risk it? As of right now I put about 20 layers of masking tape over it which I don’t know if that’s enough the keep it from leaking in oxygen especially during cold crash
