Issue : UiPath activities stopped working properly?
- Arguments are missing
- Buttons (like “Open Workflow”) no longer show
- You can’t edit or access embedded workflows
- You can’t unfold the activity

This usually points to a package runtime issue .
Fix Options :
Change the package version
- Downgrade or upgrade the affected dependency (e.g., System.Activities, UiPath.System.Activities)
Edit project.json directly
- Locate the faulty package
- Remove the
.runtimesuffix - Save and reopen the project
Quick Tip
- Close the UiPath project
- Open
project.jsonin Notepad or any IDE - Look for entries like
"UiPath.System.Activities.runtime"and remove the.runtime
