Same here. I am using Note 20 non root. Youtube vanced wont load. Stock youtube works fine. If I uninstall microG, youtube vanced works all right - so I assume microG got some problem with access my google account. Btw in settings my google account is under microg section.
Yup. That's what I'm experiencing too for some days now. Infinite loop when logged in, fine when logged out. You don't have to uninstall Microg, just remove microg google account in settings. LG V35.
This should fix it for you guys. I would also advise that you go to the settings in Vanced Manager and clear downloaded files before completing the steps -- just to make sure you're downloading and installing the correct version.
The login issue is a bug in the latest version of microg. Hopefully it will be fixed in the next release. Here's the workaround from a few pages back:
Edit: It's been mentioned multiple times so I'll repost sronweb's well written tutorial instead of my quick one.

1. Uninstall both vanced microG & YouTube Vanced
2. Install vanced microG(latest)
3. Install YouTube Vanced (version: 15.43.32)/ YouTube Music Vanced (version 4.07.51)
[Click on install > click on arrow next to version > select anything except the first two options > save > Install]
4. Open YouTube Vanced then add an account
5. Open Vanced Manager
6. Then update YouTube Vanced (version: latest-16.02.35) / YouTube Music Vanced (version - 4.11.50)
That has worked on half a dozen devices for me using the the non-root version on both rooted and non-rooted devices.
