Describe the bug

When attempting to sign in the page hangs with a spinner; it specifically fails on the /DisplayPreferences/usersettings?userId=xxx&client=emby request, which is returning a 500. Exact error visible in logs section below. Existing sessions are currently unaffected, only new sign in attempts are broken. Sometimes refreshing the page in this stuck state will complete the login, other times it will keep me on the login screen.

System (please complete the following information):

• OS: Ubuntu Server 20.04.1
• Virtualization: Docker (official image)
• Clients: Browser
• Browser: Firefox 90, Chrome 92
• Jellyfin Version: 10.7.6
• Playback: N/A
• Hardware Acceleration: NVENC
• Installed Plugins: AudioDB, Fanart, Kodi Sync Queue, MusicBrainz, OMBd, Open Subtitles, TMDb Box Sets, TV Maze
• Reverse Proxy: Caddy
• Base URL: none
• Networking: Bridge/NAT + IPv6
• Storage: local

To Reproduce

1. Visit login page
2. Enter username & password
3. Click "Sign In"

Expected behavior

I should be signed in.

I've seen this endpoint fail with this same (or at least a very similar) error before but it's always resolved itself; having no such luck this time. Appreciate any help.

Just upgraded and still facing the exact same issue :( it's actually worse now, refreshing the page never gets me through the login now.

More logs than provided above? Here's the full thing: https://pastebin.com/raw/GKU8YffN

You can see the error on the /DisplayPreferences/usersettings endpoint right at the end, from a login attempt

It looks like this is a different issue from the known bug for display preferences. Does this occur when you have no plugins? If not, which plugin causes the error?

Still occurs with all plugins disabled. It's because _displayPreferencesManager is null right? Can I set up any more advanced debugging on my instance?
