You don't tell which version of Illustrator you are using.
You don't tell what SVG effects you are or were using.
You don't tell what exactly you mean by "cancelled all effects".
You don't tell if there are any more infos about the SVG effect that "still kept loading".
You don't tell anything about the Document Raster Effect settings you are using (see Effect menu).
And you don't tell what operating system you are using.
Sorry for being a bit rude, but this kind of lack of infos constantly prevents reasonable answers and solutions.
