Erasure of my world

Good morning,

I entered my Minecraft world yesterday, and I was stripped into a dark area and was continually taking damage until my avatar died. I respawned in an area that was not my usual house (where my bed was, where I respawned every time my character died), and the message came out that it was no longer possible to Respawn to the bed because it was not there nomore.
I tried to search for my house with the coordinates, and in looking for it I noticed that the world of Minecraft was quite strange (I try to attach some screenshots), and I never found my house again.

I wanted to ask if it was possible to bring the saving back to before this happened, I spent a lot of time and it would be a shame not to be able to continue playing with it.

I thank you in advance and wish you a good day.
