Crashes when deleting effect

When i try to delete Softtube, Saturation Knob from my master channel, musescore crashes. I just put it on there to beef up the sound one time to hear it, wasn't planning on keeping it there. But it won't delete and the whole program crashes.

I'm sending a screenshot of the musescore version, my system specs and version of windows and the master channel just so you can see it for whatever reason.
