Is there anyways to save this?

I am fighting a case of fungus gnats after repotting and I think the spray is not making the plant happy. Idk if it can come back from this, or if the leaf will end up dying off. Please help! I’ve never had an issue before with any of my monstera’s. Just watered it the day before yesterday 😭
