Fatal error. Internal CLR error. (0x80131506) on Entity Framework running inside docker container on arm32

Question

I'm trying to containerize an existing application I wrote that I've been running on my Raspberry Pi 4.

The app is running .NET 8 using Entity Framework postgres (all packages are updated to their latest release versions).

The postgres database server is external to the Raspberry Pi on the cloud.

I'm running into the error:

Unhandled exception. System.Runtime.InteropServices.COMException (0x8007054F): An internal error occurred.
 (0x8007054F)

   at System.Threading.Thread.StartCallback()

   at System.Threading.WaitHandle.WaitOneNoCheck(Int32)
   at System.Threading.PortableThreadPool+GateThread.GateThreadStart()

I've been trying to figure this out for 2 days now so I'll just dump all the info I have here and hopefully someone else has run into something similar before because I'm completely stuck.

From logging I've been able to narrow down the crash to this method that is called when starting up the app (it's called in the constructor of its class and the class is registered as a singleton so it is called almost immediately after startup).

Method:

private void LoadGuildData()
{
    _logger.LogInformation("Loading data from database: Guilds");
    using (var db = _dbContextFactory.CreateDbContext())
    {
        _logger.LogInformation("Getting Guild data from database");
        _guildsByDiscordId = db.Guilds.AsNoTracking().ToDictionary(g => g.DiscordId);
        _logger.LogInformation("Getting Guild data from database done");
    }
}

The logs just before the crash indicate it reaches the call to the database but doesn't get past it:

[00:00:00 INF] Logger Created
[00:00:00 DBG] Hosting starting
[00:00:00 INF] Loading data from database: Guilds

Any help is appreciated I'm not super familiar with the low level details of this kind of stuff so maybe I'm missing something obvious, let me know if you need me to grab any more info that might help diagnose.
