my stuff is gone because the bug

I found a bug where after defeating the Ender Dragon and entering the credits, our position was recorded briefly, and then when we pressed the skip button, we immediately disconnected from the Realme Minecraft server. And when we re-entered our base map, we discovered that the shulker boxes we were carrying had disappeared. And when we re-entered the Ender Dragon portal, we didn't find the shulker boxes that we dropped, even though it was clearly visible that we had brought those shulker boxes back. It seems like the checkpoint saved us back at the Ender Dragon portal. We hope Mojang can fix this bug and restore our items that we painstakingly obtained in the End City.
