Cant build tutorial WebGL game

Hello!

I try to build my first game (FPS microgame from tutorial). Its correctly builded for PC, but fail for WebGL. I have this error:

Exception: E:\unity\Editor\2019.4.17f1\Editor\Data\il2cpp\build/deploy/net471/UnityLinker.exe did not run properly!

What am I doing wrong?

System.IO” is not available in WebGL. (Local file System)

The strange thing is that according to the task from the tutorial, i need to take this code and build it specifically for WebGL…

Anyway thanks, now I know which direction to go

It looks like the error message does not contain ASCII characters. Can you translate the message into English? Thanks!
