For all I know, this Insane diff is completely unrankable. It doesn't have to be.
Turn all of your uninherited sections into inherited ones (except the first one ofc). Use slider velocity 0,70 and speed multiplyers of 0,5x, 1x and 2x on the inherited sections to get the old slider speeds back. Resnap all notes (manually or by clicking menu bar -> Timing -> Resnap All Notes). Check the whole thing for any note timings and sliders that broke, fix them.
The map should then be pretty much the same as before, just without all the red timing sections. Those are for changes in the speed of the actual song, not your sliders.
Do that, then I'll continue modding. The map itself is nice
Btw I think offset=15 fits better than 10, not sure though.
