sudo: /private/etc/sudoers.d is owned by uid 501, should be 0 on MacOS Monterey Version 12.4

Hi I accidentally changed the owner of all the files in `/etc` directory to `joohom` instead of `root`

Now everytime I try to run a command with sudo, it keeps popping up the error

`sudo: /private/etc/sudoers.d is owned by uid 501, should be 0`

May I know how to fix this?

I have found other threads with a similar error, but they're all offering solutions for older Macs, which I have tried and didn't work.

Some other threads I found:

I'm currently using a MacBook Pro (Chip: Apple M1 Pro) with MacOS Monterey version 12.4
