UiPath.UIAutomation.Activities issue

Hi everyone!
I just updated UiPath to version 2026.0.186 STS from 2026.0.185 STS

All my UI Automation activities are now unusable, I can’t indicate a new target, I cannot edit the object (if I click on Indicate Target nothing happens, the Expand target properties button does not work either)-

-and if I place new activities they will appear in this way:

Do I need to downgrade?

If you opened the code from an existing nuget package, then install the UiAutomation full package. It will be a runtime version in your code now that’s resulting in this.

Refer this article for more info.

Nope, it’s a local project created on the same machine.

I think the correct package was already installed.

By downgrading from x.186 back to x.185 all the activities went back to normal.

Also updating packages to PreRelease did not resolve the issue.
