Hi everyone. Im from VietNam. My English is not good, hope you dont mind.
Im using Adguard and Cloudflare.
The first run Adguard after install, it's ok.
But when i enable Cloudflare, Adguard report that error bellow. And i can't even run Adguard again, even i reset setting. Adguard still don't work. Only if i restart my Mac then Adguard is ok. But the error happen again when i enable Cloudflare.

I'm on Big Sur 11.5.1.
I just install both of them, i don't change any setting or do something else, just install and use.
Can you help me how to fix this? Thank you very much.
