It crashes for me too, maybe you have the same reason. I get likes and subscribers using tiktok smm panel. Users who use cheating or masslaying / massfoloving give the system access to their profile, so the platform sometimes crashes. Tik Tok may perceive this as a hacking attempt. When the system detects this and notices a suspicious increase in activity, it restricts your actions. To fix the problem, you need to give up cheating for a while and check the operation of the utility.
