Can confirm that this is not a Bazzite issue as we have 30+ users with the latest Decky Loader, myself included.

Title needs an update.

All good, we've noted it on normal SteamOS as well. Edited title.

yeah its more when leaving desktop so better to name it like that. I tried setting game mode to be the default boot and rebooting and haven't been able to reproduce like that

[zany130]

Seems like restarting the steam client after decky was already working also doesn't load decky.

I'm thinking this happens when steam is ran with decky more than once

So the first launch works but any further launches dont

We're currently tracking an issue/race condition that's causing plugins to not load in properly and or have decky just not show up properly caused by SteamUI's webpack chunks not being fully loaded when Decky attempts to inject. We don't have a fix at the moment but I'm wondering if this might be related as well but I'm not sure.
