In that scenario, I was technically on wifi so it would have been online, but likely slow since it was public wifi on the train. I closed/open the app dozens of times, restarted the laptop, etc, but it was never able to move past the loading screen. In that case, even when I fully disconnected from wifi/airplane mode, I closed/reopened and would have expected the "offline" landing page where I could select to at least see my Downloads folder within Emby, but that never came either. Result was that I was unable to open Emby at all over that 6+ hour trip.

Last week, I noticed that my laptop ran out of disk space when downloading something unrelated and outside of Emby. Upon looking at disk usage, I noticed the local Emby Windows media directory was way too large given what I had synced/downloaded within Emby. Upon drilling into the subfolders below:

C:\Users\[Profile]\AppData\Local\Packages\EmbyMedia.EmbyTheater_svmepx4c03f7m\LocalState\data\syncItems

I noticed many old video files which I had downloaded/sync over past months that did not show themselves within the Emby app. Meaning, I had downloaded, watched, and deleted them within Emby but they were still on the disk itself. I don't know that that is at all related, but I manually deleted all the synced files there. Sometime after this when I was back on my home network, it began opening fine. I don't think I did anything special to make it work again, I just tried again later on a different connection.

For the "2nd attempt" scenario, yes, that is how it normally behaved for me when I'm on my home wifi. However, on this trip, no amount of attempts worked.

Regarding video drivers, this is technically a work computer (not on a domain), so I don't have the access to update the drivers myself. Only that which I receive via Windows Update. It does show the Intel driver version 32.0.101.6881 from June 2025.

OK that's helpful. Thanks for the info.

I've had to start using the app because of the browser refresh problem. It only opens sometimes. Sits there for an hour at the logo screen if I let it. All while a Firefox windows is open and playing movies. Restarted the server. No change. Restarted the computer. No change. Only when I went to Add/Remove Advanced Options and did a reset on the program data and it opened first time.

Test for Emby App Startup Issues

Hi,

can you please all test the WMC UI Windows App to see how that compares?

Download: https://github.com/EmbySupport/Emby.WMC.UI/releases/tag/2.234.0.0-Beta

This is mostly the same app as the regular Windows app, just with a different UI.
There's an update coming for this app which tries out some runtime updates which will get into the Windows app later.
But first of  all, we need to know whether you'll see the same issues with the WMC UI app (if not, this would also be helpful). 

Thanks
