Issues - Windows Platform
There are issues some users might run into on Windows when using Godot and GodotSteam.
No SteamClient023 Error
Some people have experienced this error when running their Windows game on Linux or Steam Deck through Proton; though it only happens with Steamworks SDK 1.63.
The reason is SDK 1.63 is only supported on Proton 10.0-4 or higher, including Experimental.
At the time of writing, you must use 10.0-4 or Experimental to avoid this error. Alternatively, just create a native Linux build and ship that instead.
