Which file store all error logs in the user build

Unity Engine

Hello there,
I want to collect log files from Windows standalone users to detect errors in the build. But I am completely clueless which file is storing these errors? Or are error logs only generated for development builds?

Google “unity runtime log files”

I already read those search results. Which file I should look for in user device? Editor.log? Player.log?
output_log.txt?

Well, is the end user going to have an editor only log on their computer?

It should be pretty clear you want the player.log: Unity - Manual: Log files

Player.log only have these lines:

Yes it is mate.

It will contain the Debug.Log outputs and other logs/exceptions that happen during a built project. There just happens to be none in the example you’ve shown.

I use it on a daily basis when testing builds (which you should do regularly).

If that game is not yours, the developer may have disabled or filtered the logs. You should be able to redirect the log output to a specific location by using the -logFile <filename> command line option when starting the standalone application.
