Seems to happen if WiFi variable in WifiPage.tsx is null/undefined. I don't have wifi adapter plugged into my PC, so I think that's why it's failing to start (CachyOS)

Ok, thanks for the feedback. I was wondering if the network related icons on the bar are working (if the bar can be displayed)? I fixed the systemindicators on the bar earlier and if it's working I think I'll be able to pinpoint the location of the error.

I wasn't able to get the quick setting widget working at all. Clicking on the application on top left works fine, but anything on top right (the quick setting widget that includes network + sound and other things and even the power button) wouldn't work.

I tried returning just an empty component for the wifi and it fixes the problem, fwiw.

Oh, well done! I just pushed a fix for exactly the method you used, I can't believe I forgot about the problem in quicksettings when I was fixing systemindicators earlier 😂.

Just pulled and tried it again and still same issue,

https://github.com/acdcbyl/Dotfiles-arch/blob/main/ags-gtk4/widget/Quicksettings/pages/WifiPage.tsx

That component is the culprit at line 41.

I haven't really looked at the components in detail, but probably because in QSWindow line 325, it's still calling the WifiPage component and so null pointer is being caught at line 41.

[acdcbyl]

It looks like you are right, maybe there could be a similar issue regarding bluetooth... I will try to judge it for all components tomorrow.

I basically commented out the WifiPage comment out of QSWindow and yeah, works just as if returning null. I guess issue then is that the box still remains in the window, it's just empty.

Otherwise, looks pretty good, good job!
