Ran successfully but no root

[Oreeeee]

Hello, I'm trying to root API 29 x86_64 AVD. Magisk app gets installed, but there is no root access. After rebooting the AVD for the first time there was a "Magisk needs to restart your device", but it didn't matter did I click Yes or No, the root disappeared right after.

Log:

I fixed it (for now at least). I forgot to disable mitmproxy and this virtual device lacked the SSL certificates.
