"page not found" for one of my products after new update

For your reference, I'm talking specifically about the product above.

This product's page worked like normal (click the thumbnail / link and it opens the page up) before the new update. However, after the new update, it leads to a "page not found" page instead of the product itself.

I checked all the other items, and this is the only item on my shop (alongside the listings from other shops like Payhip / Booth / Gumroad) and they work as intended.
