Why is UiPath Robot crashing with the following Error message: "No open windows found for 'credentialuibroker.exe'. Please check if the application is running." and how to troubleshoot the error?
Issue Description:
Unexpected crashes of the UiPath executor while running a job may occasionally be encountered. These crashes are commonly paired with the error messages:
"Unknown software exception (0xe0434352) occurred in the application at location 0x00007FFE870FAB89"
or
"UiPath.UIAutomationNext.Exceptions.ApplicationNotFoundException: No open windows found for 'credentialuibroker.exe'. Please check if the application is running."
Root Cause:
These error messages typically indicate issues related to the .NET Framework, corrupt system files, incompatible drivers, or potential malware infections. These causes lead to the UiPath executor becoming unstable, resulting in these crashes.
Resolution:
To troubleshoot this issue, consider the following steps:
-
Update or repair .NET Framework: Download the latest version of the .NET Framework from the official Microsoft website. If the.NET Framework is up-to-date, attempt a repair operation, as this is often the underlying cause of unknown software exception errors.
-
Perform System File Check (SFC): If corrupt system files are causing this issue, run an SFC scan. Open the Command Prompt as an Administrator, type 'sfc /scannow', and then press Enter to start the scan.
-
Check for malware: Execute a complete system scan with a reliable antivirus software to identify any potential malware that may be causing this error.
-
Update system drivers: Ensure that all system drivers, especially graphics drivers, are up-to-date. Outdated drivers can sometimes cause the UiPath Executor to crash.
