Editing Clip path - Round corners leads to crash
Summary:
Receive a system crash consistently when editing this file, and have experienced it in the past with others, where engaging the tool to round the corners leads to a crash window popping up and a dialog.
Steps to reproduce:
- On Windows 11....
- open Inkscape
- Open the file (attached to this report)
- Select Layer g14
- Turn on "show clipping path(s) of selected object(s)"
- Select the four corners
- Click on "Add Corners LPE"
This will CRASH the program on my system, resulting in this screen.

What should have happened?
I should have been able to proceed with rounding the four corners of this shape freely. I know there are more edges on the shape, but something with adding this effect causes it to crash every time.

Version info
I wish to round the clip path on the "canvas" artwork. In Inkscape, Select the shape, press N to go to Node editor, turn on the ability to edit the clip path, select the four corners, click the "Round corners" tool, and the system will crash.
