SideSync App will not open on Android device

I downloaded SideSync on my Android phone but it keeps saying SideSync keeps stopping.. I've already tried to restart my phone and uninstalling and reinstalling but that hasn't worked. I've called in the permission settings in the app setting seems correct . Can anyone help me with this?

SideSync, unfortunately, has long been deprecated. It is no longer supported, so newer OS versions will likely return these errors.
