ZeroTier high CPU usages on Ubuntu 20.04

I’ve got a Ubuntu 20.04 server that is facing a weird problem. Sometimes I notice that the CPU usages is very high. After checking with htop & top it seems like the problem is causing ZeroTier. I’ve noticed this for a few days. I’m not even using ZeroTier at that moment. I’ve waited a few hours too because I thought It’ll fix the problem after some time but it won’t. I use ZeroTier for accessing my server outside the home. If I enter sudo systemctl restart zerotier-one it immediately restarts ZT & fixes the problem. I don’t know how to collect logs for ZT otherwise I would share here. How to fix the problem ?
