I am unable to open SVG files properly, what should I do?

If you select the curved text in Inkscape, then Path>Object to Path, then save the SVG, it will import into LB

How about this idea? Make your own object with the native tools in lightburn? 30 second job to draw a circle, offset outward and make a text box. Getting the text to show inside the circle is another 19 seconds job: change text to path, off set a small fraction and delete original objects. Less than a minute and 3 new skills learned. Oops. Forgot the curved line of text underneath. Add another 24 seconds to apply text to line.
