I can't transform the "Body" Mesh anymore in Edit Mode

I’m working on a body mesh for a personal project and i think i made a mistake somewhere because i modeled the hand then joined it to the main body then i couldn’t transform the body anymore.
The manipulator is "locked" on the hand meaning that whatever part of the hand mesh i select, it appears but when i select a part of the body mesh, it doesn’t and doesn’t "cancel" the selection too.

Here’s the link to the file if you want to look for yourselves what the issue might be.

Edit : File has been deleted since the issue got solved ! (Thanks again)

• Snaping isn’t enabled

Don’t know if the explanation is clear enough but i can try to explain better if you need.

Thanks for the help and your time!
