Crash when steam is closed

Checklist

[x] I have checked the known issues page for this problem.

Describe the bug

When steam is closed, polybar is still running correctly, but the dwm module disappears. Closing here means closing it completely, not just clicking the x and leaving it in the tray.

Expected behavior: dwm module crashes and disappears.

Actual behavior: dwm module should not crash.

Was it working before?

No, I just installed polybar-dwm two days ago

To Reproduce

Start steam and close it by clicking: Steam > Exit
