PARM error with custom brushes on multiple different files

[Delysse3611193486u3]

Hello,

I have created multiple different files in illustrator v27 to v29, even tried beta. I create digital drawings from photos with my own custom brushes. I have used the elipse tool to create a tapered line art stroke and used the elipse tool to create a feathered brush with the elipse tool, a small solid circleinside a transparent large circle, which I blended using the blending mode with specified steps of 100. No matter how many times I recreate the brushes or start new artwork, the same "PARM" error message happens or "there was an error in applying brush stroke". I can work around by doing a single brush stroke, waiting for it to load and saving my work every 20-30 seconds, else when it inevitably crashes I lose my work. If I do more than one or multiple strokes in quick succession illustrator "not responding" and greyed out screen appears and I have to kill the program externally or through the tab right click close (though this sometimes doesn't work). My settings/preferences don't save upon reopening and if I haven't saved it close enough, I lose everything!

I called tech support and the problem was resolved momentarily, but it lasted only minutes. 

Please HELP!

100 blend steps do not go well in a brush. 

I do not think you need that many. Try fewer, like 20 or 30.

And then also: please tell us the hardware specifications.

Thank you, I will try to convert it. I got the step size from a video tutorial.

I have yet to see a video tutorial in which the presenter tells you about the consequences of too many blend steps.

Agreed, and tech support just gave me generic cleaning options. Very helpful, thank you. I can gather that the more steps in blending modes, the higher capacity it takes to generate the stroke.
