Build Problem in unity 2019.1.9f1

Hi

I’m trying to create a two-player game there is a little problem !!!

Game is Turn-Based Type

Each Round I wait until that the player who is his turn do everything and then I send his logs to server and server send them to other player and other player replay that and turn will change.

when I build my game and test it if my unity test became player one it works for three or four rounds But when my test build became player one it doesn’t work more than two round and I think it’s because of my build.
I spend about two days and found nothing to help me. But I think it might be of my .NET!!! it’s 4x Equivalent

Builds will happen if there are no errors, this is probably your “programming”.

When you didn’t have any error when you are building your game so you must improve your scripts.
