Desktop app issue on latest update

[Lonewolf1061]

The desktop app is hanging up when you right click on the app and pull up the channel list on the context menu. When you select a channel the app says please wait and the tray icon goes red. After about 30 seconds the tray icon goes green and the app is still saying please wait. Have to close the app and reopen it. Only way to start it is to choose a channel from the TV guide and it works normally. Did a full clean reinstall and the problem persists. The previous version did not do this, just this latest update. I am running version 5.2.2.2.11017. Wondering if anyone else is experiencing this. 
Running Win 10 21H1 with all the latest updates. 
Attached are the log files.

The desktop app is hanging up when you right click on the app and pull up the channel list on the context menu. When you select a channel the app says please wait and the tray icon goes red. After about 30 seconds the tray icon goes green and the app is still saying please wait.

Could you please repeat this, and let me know what time you clicked the channel, so I know exactly where I'm looking in the logs. Make sure you use the 'log files' button in the web app to collect the logs, because it tells the application to flush the logs to disk (otherwise your logs can be missing important stuff).

I tried the steps you described, and it was fine here.

I just duplicated the issue again and the got the logs from the web app. Started the desktop app at 12:10 pm.

If you look in D:\Pause Buffer\ when you try doing this, does a live tv buffer file get created, and do you see the file size growing?

[Lonewolf1061]

The D:\Pause Buffer is empty. When the channel is trying to load I could see a .ts file getting loaded, but as soon as the tuner disconnects it deletes the file. When you right click on the tray icon to show status the app connects to the tuner but then after 30 seconds it disconnects from the tuner. The app keeps showing "...please wait..." until you close the app. Only when you use the context menu to pick a channel, if you pick a channel from the TV guide from the menu it works fine. The web app is unaffected by this.

I'm wondering if the latest cumulative update from windows that was installed on 10/23 is corrupted because I upgraded to the new version of NPVR shortly after that. I did run the SFC /SCANNOW and it showed no integrity violations.

Yes, that is the expected behaviour, but if you copy the file part through that 30 seconds, the copy will stay when the live tv attempt fails. Does it have anything in that file.

I am seeing the same issue here.  NextPVR.exe plays fine from the EPG but via the right click menu a blank screen followed by this error after a long timeout likely at StartLive@done perhaps when I click the screen.

Sub, I did capture a partial video file before it timed out, so the pause buffer seems to be working, but the video is not showing in the UI.
mvallevand, I just got the same messgage when the app crashed the last time I did this....see below

Code:

just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

Can you let me know if this helps?

[mvallevand]

Yes that fixed it for my testing.
