When I start in the LAN world where I always play, my session is deleted and my items are deleted, the end chest appears empty and my pets do not get up. Everything I had in my inventory disappears.

Good morning, I have a problem with my session to play in a lan world where I always play, I lost my inventory completely, my end chest is empty and my pets are not responding, as if I were not the owner of anything, but it is the same account that I always use, sometimes it throws me to spawn and other times I am where I disconnected, but without my current inventory or ownership over my pets or the end chest.
