UiPath Studio crashes frequently

Help Studio

Hello all,
since 1 month i have problem with frequently UiPath Studio. Studio just crashes spontaneously and makes my blood pressure rise since all (unsaved) changes that i made in development can’t be restored. I came into phase that i save every little change that i make which is just annoying.
Error that i get is always same (log):

14:08:15.2021 => [ERROR] [UiPath.Studio] [1] Dispatcher Exception: System.Runtime.InteropServices.COMException (0x88980406): UCEERR_RENDERTHREADFAILURE (0x88980406)

  • at System.Windows.Interop.HwndTarget.UpdateWindowSettings(Boolean enableRenderTarget, Nullable`1 channelSet)*
  • at System.Windows.Interop.HwndTarget.UpdateWindowPos(IntPtr lParam)*

  • at System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Int32 numArgs, Delegate catchHandler), HResult -2003303418*

I already installed and reinstalled last 3-4 versions of UiPath Studion on my laptop and (at least i think) tried everything. But i always get this same error with the crash.

Has anyone issues like me? If yes, can someone tell how do i solve this annoying problem.
Thanks in advance,

Sascha

Hi @flave

This error typically occurs when there’s an issue with the graphics driver, or when there’s a problem with the rendering of UI elements in an application.

Here are a few potential solutions to resolve this issue:

  1. Update Graphics Drivers: Make sure your graphics drivers are up-to-date. You can do this by visiting the manufacturer’s website for your graphics card and downloading the latest drivers.
  2. Run in Compatibility Mode: Try running the application in compatibility mode for an earlier version of Windows. You can do this by right-clicking the application’s executable file, selecting ‘Properties’, going to the ‘Compatibility’ tab, and checking the ‘Run this program in compatibility mode for:’ option.
  3. Disable Hardware Acceleration: If the application you’re automating has a setting to disable hardware acceleration, try turning it off. This setting is often found in the options or settings menu of the application.
  4. Increase Virtual Memory: Sometimes this error can be caused by a lack of virtual memory. You can try increasing the virtual memory (paging file size) of your system.
  5. Check for Windows Updates: Make sure your system is up-to-date with the latest Windows updates. These updates often include fixes for various issues, including UI Automation errors.
