It does not work when use export project as client

[arkotters]

I implemented my code almost entirely following the format of the demo example.It is all going well when I run in godot. However, as long as I use export project as client, I can not use any rpc function, although connect_socket successed. Then I restarted the game and rebuilt the lobby, and everything returned to normal.I'm not sure what happened, and it's difficult to investigate. Can you reproduce this problem?if possible, please give me some help!
I used the default export scheme without additional settings

@arkotters I don't have this problem, but can you give me details about the version and platform?
Godot version, plugin version, your tested platform, etc.
