Hi Raymond, There has been an issue in Qt, where it was very picky with the <style> tag in the svg [1]
This is solved in newer Qt versions (and newer QGIS for Windows builds) but is still present in the early QGIS 3.16 builds based on older Qt versions. The quick hack is to replace the <style> tag with <style type="text/css"> in the svg. Or upgrade to the latest QGIS version.
