How to Fix Mouse Not Working Error in Marathon Server Slam

According to Bungie, the mouse not working error is chained to streaming and launcher platforms like Discord, OBS, and Steam. You might end up facing this error if you are trying to stream Marathon or capture gameplay using software. Here are the fixes you can use to get rid of this issue in Marathon Server Slam:

If streaming, try streaming the whole screen and not the Marathon game window specifically.
If not streaming, or if the above doesn't work, try disabling Discord or Steam overlays.
- For Steam, click Settings → In Game and then toggle off "Enable the Steam Overlay while in-game".
- For Discord, click Settings → Game Overlay and then toggle off "Enable Overlay" or "Enable Legacy Overlay"
- Also turn off game detection through the Register Games tab.
Some third-party utilities can also introduce this problem. Try closing any screen sharing, screen capture, or screen measurement utilities.

Disabling your game overlay in Discord solves the mouse input issue in Marathon Server Slam.

If you're still facing this issue after following the aforementioned steps, then try turning off Discord completely. Once you turn off Discord, you will notice that your mouse input is back to normal. Unfortunately, if the error is still persistent, keep your patience and wait for Bungie to drop a hotfix addressing this issue entirely.
