Perhaps. UiPath download lowest version of RestSharp matching to all dependencies (106.15.0). If you remove WebAPI.Activities package RestSharp should automatically downgrade to 106.10.1. Please check if Jira Scope working after that. If yes it means that Restsharp version was the issue. workaround → older version of WebAPI.Activities use older version of RestSharp (then you can downgrade this package and we have no conflicts)
