Frequent errors after updating to Studio 2026.0.196

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?

I can reproduce it in my environment (2026.0.196STS). There might be a slight chance of a specification change, but I believe it’s more likely to be a bug.

Thank you for your verification.
I’m glad to know that it’s not just my environment.
For now, I have submitted a bug report. This bug prevents my project from running, but I guess I have no choice but to wait for a fix…

Here is some additional information.
The error that occurred when placing a trigger scope inside a “Parallel” has been resolved with the update. However, if you place a trigger scope inside the Handler block of a “Cancel Scope” or inside an “Else If,” the error “Trigger must be the first activity in the workflow.” still occurs.
