My product was launched by someone else, but I can’t be the Maker Or Hunter😭

Hey，guys， Have you ever encountered this situation? 😐 The product was launched by someone else, but I couldn't contact that person and couldn't become a maker. What should I do? I was very depressed.😤😤😤 I prepared for the launch for a long time, but I didn't expect that someone else would launch it first.😭😭😭
