In Blender 4.4, the render engine enum BLENDER_EEVEE no longer exists. I fixed it by replacing all references to BLENDER_EEVEE with BLENDER_EEVEE_NEXT. Plugin works fine now.
You need to edit line 1392 and line 1393 to look like this
if bpy.context.scene.render.engine not in ["CYCLES", "BLENDER_EEVEE_NEXT"]:
bpy.context.scene.render.engine = "BLENDER_EEVEE_NEXT"
