server.close_all() freeze the whole application

[GianptDev]

System: Linux Mint 20.4
Python 3.10.5

I've made a gui application for a simple ftp interface, the application run the server inside a thread.
This is the code of the button:

def stop_server(self) -> None:
	server = self.server
	self.server = None

	server.close_all()
	self.server_thread.join()
	
	self.server_thread = None

If I execute this script on windows and i press the button it will work normally.
If I execute this script on Mint it will freeze the whole application.
