i purchased cider few weeks ago it worked fine for a week or so then it started crashing all of a sudden i tried reinstalling it using it's portable version nothing seems to work for me iam attaching a video how it's crashing for me i just updated it a few days ago to the latest version 

Same exact problem. I've had to switch to their deprecated, free Cider platform 1.6.2. This has happened a few times to me with updates and I'm at the point where I'm never going to update it after this one gets fixed. It's frustrating.

FINALLY found a solution by shelling out for the supporters patreon...ridiculous

anyways 
Try deleting %appdata%/C2Windows and %appdata%/sh.cider.sabiiro
