Is there any way to get my Minecraft world back?

I recently removed my Xbox account from my Xbox and when I added it back, my Minecraft worlds from the last couple months were deleted.

I looked back at what it said when I deleted my account, and it said that files that haven’t been uploaded yet will be deleted. I tried clearing my cache to get those to re-sync with the game – nothing. Deleted and reinstalled the game – nothing. Uninstalled the beta and redownloaded – nothing. Is it gone for good or do I have hope?
