Reproducible with: 6000.0.52f1, 6000.0.68f1, 6000.3.0a1 (4592b02ab560), 6000.3.9f1, 6000.4.0b9, 6000.5.0a7
Not reproducible with: 2022.3.71f1, 6000.0.51f1, 6000.2.0b2 (2bdac9ac0d74)

Notes:
-Plugin source is attached as "GraphicsPlugin.zip"
-This can be worked around by either the Package installing the plugin into Assets/Plugins or bypassing the Package Manager completely
