Windows 11 App Refusing to Load

[Natelanxon 29]

Hi. I just installed Emby from the Windows 11 Store and it refuses to open. I checked Task Manager and after clicking the app, I briefly get one instance of Emby.Client.WinUI appearing but then disappearing after about 2 seconds and then nothing happens. I checked Windows Event Viewer logs for instances of a crash and can find nothing. What can I check to find something helpful in diagnosing this problem?

This is my system:
Edition    Windows 11 Pro
Version    25H2
Installed on    ‎04/‎10/‎2025
OS build    26200.8655
Experience    Windows Feature Experience Pack 1000.26100.315.0
 

Emby installed version is 2.315.2.0

Thanks

can you see your server on the web app from the same machine?

[Natelanxon 29]

I can yes. I used the web app when the native app wouldn’t load. I’d prefer to be able to use the native one though if there’s a way.

hmm, try updating to the latest windows version, it should be under the optional update section.

plan B, uninstall and reinstall.

[Natelanxon 29]

Tried these. I also tried updating to the preview update as well. Nothing seems to do anything.

Are there any logs in this dir?

C:\Users\%username%\AppData\Local\Packages\EmbyMedia.EmbyTheater_svmepx4c03f7m\LocalCache\logs

That might show what's going on.

Was that checking the "Application" log in "Windows Logs" for Source: "Application Error" relating to the Emby app ?

A suggested the logs may have some clues

• Is this a cloud VM?
• Did you perhaps enable and use the original Windows administrator account where you don't need/have any elevation requirements and you don't get any UAC (user account control) prompts?
• Can you run other Windows Store apps without problems?
• Is your machine member of a Windows domain?
• Do you have any group-policies configured which might prevent the launch?
  => run gpresult.exe /v

And please look for logs like @Neminemsuggested.

Thanks

No, that folder doesn't exist. Everything up to /LocalCache is there, but there is no log dir.

It's not a cloud VM but it is a VM. My other apps, including those from the Windows Store, all work fine. It's only Emby that doesn't launch.

I also tried launching the app as an admin but that didn't make a difference other than to give me the elevation prompt by Windows.

It's not part of a domain and there shouldn't be any group policies as it's a pretty standard Parallels VM that runs a handful of apps.

I'm guessing the nature of it being a VM is part of the issue but it seems strange my other apps work fine. I wonder if there's anything I can try?

Incidentally, the old Windows Theater app worked fine. I've just pulled that from Github to test and it works. I guess if nothing else works I can still use the old version.

We could see if SysInternals Process Monitor gives some clues. You can download from the microsoft page here

Unzip and accept the EULA and you can set up a filter of Process Name containing the word Emby

and at the end when the app exits, save all filtered events as a PML and zip and upload using a link I will send you

You could also if you do not mind, launch event viewer and open each of the Application and System Windows Logs and save each as an evtx and zip and add to the upload

When you do the test, check task manager and make sure there is no emby client app process running - if you find any, end the process 

Then launch process monitor, start capture 

Then launch the new Emby Windows app

When it fails to launch, stop the capture and save as PML file, zip and athen save the two evtx files

Thanks

I've done this and will share with you via the link you DM'd me.

@NatelanxonIs your VM setup as ARM64 ? There is a lot of log lines in the PML relating to XtaJIT64

 

 

[sa2000 790]

I can answer my own question - i can see this in the Environment Variables in the PML file process starrt

 

;	PROCESSOR_ARCHITECTURE=ARM64

You are probably the first person to run the new app version on ARM64 on Windows
