The drag-and-drop function has stopped working on the IPC

After creating a new project, dragging and dropping the steps into the editing area keeps failing.
I can’t perform the drag-and-drop operation in Vision. Even after restarting the software, it doesn’t work. However, it works after restarting the IPC. Why is that?

This issue is caused by the remote software (Sunlongin). It can be resolved by changing the version of the remote software.
