Uipath is not opening - showing an error - "Object reference is not set to an instance of an object"

Hi guys,

It’s been a long time since I have posted.

Here I am back with a question . Please help me with this.

In community version, when I try to open UiPath, following message is showing.


After clicking on “OK” button, UiPath has been stopped automatically.

Thanks & regards

Hi @nirmalya.sarkar

Welcome to UiPath community

Can you try to Restart UiPath Studio and clear the cache.

Try to Reinstall the UiPath studio.



Hi @Gokul001 , can you please tell me how to clear cache from UiPath??

Thanks & regards

Hi @nirmalya.sarkar,

To clear the cache in UiPath, you can follow these steps:

  1. Close all UiPath Studio instances.
  2. Open the Run dialog by pressing the “Windows key” + “R”.
  3. Type %localappdata%\UiPath and press Enter. This will open the UiPath cache folder.
  4. Delete the contents of the folder.
  5. Restart UiPath Studio.

Hi @Gokul001 , I have cleared all the cache & I have installed it again.

But it is not working.

What can be the other solution? Please guide me on this.
