This was working for me until this past week, I have the same issues others mentioned with the "security notice" popup. Even when I did re-install CapCut and checking the box to remove user file settings I still received the popup on a new/uncracked version of CapCut. I had then find and delete a log file for CapCut so the popup would finally disappear.
Please @iosdevice do what you can to fix this if possible and thank you, it was working like I said until this even on the latest versions, but the popup appears as soon as you turn on the Wifi and are connected to the internet after running the crack.
