Level3: assignment2, cannot use UI explorer

[Natapong (Natapong Raojutitam)]

Hi @doudouzhang

Could you please confirm your project component
and try to update [UiPath.UIAutomation.Activities]

If this update package cannot solve your problem, Please refer below article:

Getting "Could not load file or assembly 'UiPath.Interop, Version=9.0.6844.26814' error

Hi @deepak1745 I would suggest a fresh install of UiPath Studio to solve this issue. You could also try a few things to see what the cause is: is it an older project that was recently opened in newest release? what is the project name? does the issue happen on a blank, new project?

I hope this information will be useful for you
