All these processes normal?

The following image shows the screenshot of my Task Manager.

These several duplicate processes of UiPath normal? I just started my project and thats whats in the Task Manager.

The reason why i ask is randomly UiPath hangs without any error. Then i have close UiPath from Task Manager and start again.

The following is the Taskbar

Yes, starting 21.4 we have a multi-process architecture for Studio. This will improve the overall performance and allow better usage of resources when available.

Why is it always hanging as you can see from the image of my taskbar. It just randomly hangs with Error

Could you maybe share the error? (if it is not on the foreground, maybe you can bring it to the foreground with an ALT+TAB).
