"Object Reference" error when indicating an element in studio

I have recently started encountering a bizarre error in Studio. I’ve been using UiPath for about three years without issue, but today whenever I use any activity with an “indicate element” function, I am getting an “Object reference not set to an instance of an object” error with no further details.

I can drag the activity (I’ve tried element exists, click, type into, etc) into the workflow, click “indicate element”, point to an element, see it highlighted in blue, but when I then click on it, I get an error box stating “Object reference not set to an instance of an object” and Studio reappears with no selector added to the activity.

I can open Ui Explorer and use it to indicate the same element without any issue.

The only thing that has changed recently is that my company completed an Enterprise Trial for Orchestrator, and once that completed I had a company administrator login to my machine and disconnect UiPath Assistant from the Orchestrator connection.

Has anyone else ever seen this particular error? Thanks for any insight you can provide!

Can you please provide the %localappdata%\UiPath\Logs<date>UiPath.Studio.Project.log ?

Apologies for the long delay, I got sidetracked and never made my way back here. I ended up solving the issue by doing a clean reinstall of Studio.
