There's a lot worse situations about copyright.

Blocked in country is one thing. If they are going back worldwide, it's easier for them to take down your whole video. They may even give you a channel strike if you try disputing it. However, as long as you're not monetising, it won't be that serious; however you still used copyright content and they(owners) still have the right to take down your video.

The outcomes are hard to predict, so it's easier to stick to the royalty free, or you can try inputting audio from youtube audio library replacing the copyrighted song.
