When I undo after cutting and pasting on a vector layer, Clip Studio Paint force closes.
We have confirmed a bug where Clip Studio Paint force closes if the [Undo] command is performed after using the [Cut and paste] command while selecting a vector line.
This bug will be fixed in a future update.
We apologize for any inconvenience.
Workaround
Instead of using the [Cut and paste] command for vector lines, instead use the separate [Cut] and [Paste] commands from the [Edit] menu.
You can also use the following shortcuts.
For Windows
Ctrl + X (cut), Ctrl + V (paste)
For macOS
Command + X (cut), Command + V (paste)
