In Studio, I am placing trigger activities (like “File Change Trigger” and “Global Variable Change Trigger”) within a trigger scope. When I position this trigger scope inside a “Parallel” activity, an error occurs stating, “Trigger must be the first activity in the workflow.” Also, even outside the parallel, if I place multiple instances of this trigger scope within the same XAML, another error appears saying, “Only one trigger per workflow is allowed.” This behavior persists even in new projects.
Additionally, there have been instances where XAML files marked as “Exclude from Publish” were included in the compilation during Studio’s compile time, leading to errors (though the error content itself was correct). Through various attempts, this seems to have resolved itself for now.
The project is Windows-based. I have tried reinstalling UiPath Studio, clearing the cache (%LocalAppData%\UiPath, %AppData%\UiPath), updating System.Activities, and deleting .local, .project, and .settings files within the project, but nothing worked.
When I open the same project file on a different PC using Studio 2026.0.182, it functions normally. Moreover, a project published with this Studio version runs perfectly on UiRobot version 2026.0.196.
Is this error happening only in my environment?
