Importing a SVG file causes an IndexOutOfRangeException

[Eric13246]

I encountered a bug where importing a SVG file causes an IndexOutOfRangeException. When that happens, the program does not crash, but nothing gets loaded in the working canvas.

To Reproduce

1. Have an SVG file that was exported from Adobe Illustrator 2022
2. Click on File > Open File
3. Go to the location of the selected SVG file and click Open
4. In the Target image window, leave the default settings and click Create!
5. Click on ? > Open session log to see the error's stacktrace

Expected behavior
The SVG file should be properly imported in the working canvas of LaserGRBL.

Hardware and software configuration (please complete the following information):

• Windows 11 Pro 22H2 version 22621.819
• No engraver connected to PC
• LaserGRBL version 4.9.4

Additional information
The SVG file was generated with Adobe Illustrator 2022. I don't know if this could impact the resulting SVG file, but I just wanted to include that info for reference.

Stacktrace found in the logs when importing this SVG file:

Hi, just to give you an update...
I have found the issue, and I am working on a solution.
Hard to find because SVG has a lot of variant so I should deeply check that the fix does not cause more issues :-)
