The dragon's egg disappeared from the end once the dragon was defeated

I have a problem and wanted to see if they could help me. In my world playing survival, the dragon egg of the end was lost. When I resurrected it 1 time and defeated it. The egg disappeared and I could not locate it, look everywhere and even at the point of repair. But I don't have it. I would like to know if you can help me to achieve it again or what I could do in this case since I cannot restore the world of the end as in the previous version. PD: I know that it is a failure to report it as such as well. It's the PS4 bedrock minecraft
