So I use paper MC for a home server and Ive been having a issue where random a chunk will be reset or a tree will be cut in half or a building will also be cut in half and I don't know what this is or have to stop it. The version I have is 1.21

This sounds like player activity with the lack of information you've given
By the way, update to latest 1.21.1
