"SEB freezes while initializing the user interface."

[naveensethupathy]

SEF freezes during the initialization of the user interface. I'm using the latest version, but it's not working for me. I have McAfee antivirus installed, and the screen hangs for an extended period

[strau0106]

Without logs there is nothing anyone could do about this.

[dbuechel]

Exactly, please provide the log files of the affected session as mentioned by @strau0106. They can be found under %LocalAppData%\SafeExamBrowser\Logs.

[naveensethupathy]

@strau0106 please check this out 2024-03-15_06h54m25s_Client.log 2024-03-15_06h54m25s_Runtime.log

Okay, something is definitely interfering with SEB, the startup procedure can't even be terminated successfully:

[dbuechel]

yes it works fine in my friends computer

That would indicate that an issue with your computer or its configuration is more likely than an issue with SEB itself.

did you solve it? bro

@davidyucheng Try to abstain from unnecessary comments. We need a (ideally reliable) way to reproduce an issue, otherwise we cannot do much in most cases.

@SATHWIK-2004 Do you use something like wallpaper engine?

[dbuechel]

@SATHWIK-2004 Something (or rather some third-party software) interferes with the kiosk mode induction of SEB. Specifically, the desktop monitoring seems to be failing:

2024-05-14 13:05:49.423 [29] - WARNING: [DesktopMonitor] Failed to get currently active desktop!

Try to consecutively exclude resp. deactivate any potentially interfering software. It might also be an anti-virus software which is interfering, in case you're using one.

[SATHWIK-2004]

I have deleted the log files many times but - this problem is not solved

I uninstalled the safe exam browser I deleted the log files and I tried all methods that mentioned ! Worst experience with the app ! More bugs less user experience Worst app I have ever seen

[emberfox205]

Hello, I have also encountered a similar problem. Though it seems to begin at the moodle page. There was a class in my university that went over the installation steps for SEB, and I was the only one with this issue. The version issued by the school was 3.5.0 but this issue appears with the latest version of SEB as well.

Despite that, I can still access SEB, but then another issue pops up, which is the frozen screen while initializing user interface:

[dbuechel]

@emberfox205 Thanks for the information. I can't see anything suspicious in the log files, but it is apparent that the initialization of the application does not complete. Can you find any related information in the Event Viewer system application (under Windows Logs > Application)?

Either way, please update to version 3.7.1 and try whether that resolves your issue. If not, I'm afraid I'd need a way to reproduce the issue, otherwise there's not much I can do without a clear idea of what could be the problem.

[emberfox205]

@dbuechel All the event logs with the source SafeExamBrowser are just Service Started Successfully. Updating to 3.7.1 did not work either. I am currently in Windows Insider Program (Dev Channel) so that might interfere with things. I'll report back after resetting the device.

[emberfox205]

@dbuechel After unenrolling from Windows Insider and resetting my device, I was met with a different issue: "ERROR: Caught unexpected exception while performing operation 'LazyInitializationOperation'!". The most recent info in Event Viewer are Windows Error Reporting's MoAppCrash and AppxDeploymentFailureBlue

[dbuechel]

@emberfox205 Please update to the latest version 3.7.1. If the issue still occurs, ensure that you have given SEB permission to access the location services (see Settings > Privacy & security > Location in the system control panel of Windows).

[emberfox205]

@dbuechel Thank you very much. The issue has been resolved.
