Uipath.session.csharp.exe Exception (0xe0434352)

Hey @yuri.santos

The error 0xe0433434 is a generic .NET Framework exception code. In the context of UiPath, this typically means that an unhandled .NET exception occurred during the execution of a process or while starting the UiPath application itself.

1. Repair or Reinstall .NET Framework

  • Go to Programs and Features > Find .NET Framework > Choose Repair (if available).
  • Or download the latest supported version from Microsoft:

2. Repair UiPath Studio

  • Open Control Panel > Programs and Features.
  • Select UiPath Studio > Click Repair.

3. Check Event Viewer for Details

  • Open Event Viewer > Windows Logs > Application.
  • Look for an error entry near the time of the crash with more context, possibly including:
    • Stack trace
    • Faulting module
    • Application exception message

4. Update or Reinstall Packages

  • Open the Manage Packages pane in UiPath.
  • Try updating or reinstalling dependencies, especially any custom libraries.

5. Run Studio in Safe Mode

  • Launch UiPath Studio in Safe Mode (without loading all extensions) to isolate the problem.
  • This can help if extensions or packages are causing the crash.
