Question Why *unity file has multiple serialization format

I just cloned other's unity project built with Unity 2022.3.3f1. However when I tried to open it with Unity 2022.3.5f1, it shows the *.unity file cannot be open since "File may be corrupted or was serialized with a newer version of Unity".

I know that almost all Unity files use yaml as serialization method with specific id and version. So I thought there might be it's LTS so it's quite normal to be not compatible with old version. However, when I open the scene file "BossScene.unity", it shows something like below:

version https://git-lfs.github.com/spec/v1
oid sha256:0cf95f1ada464a7d248d0bfcddbaf9119224a7c34bf1c14a066f56b53b3c2fca
size 121692

It seems like not a normal *.unity scene file, much more like a compressed file instead (bc of the md5 code). I searched over internet and it said it's probably released by AssetBundle format. So I wonder how could I recover the normal *.unity scene file from it?

 

Okay my mistake, clearly it's been hosted on git-lfs
