DXP Unable to find a module by assembly error

[nkuebler-nafinc]

We are receiving the following error in our DXP integration environment when adding the notfound handler to our solution. The error causes the CMS to display a friendly 500 error page and is inaccessible to content authors. The non CMS or visitor portion of the site is unaffected.

We are using the latest (version 5.0.8) of Geta.NotFoundHandler.Admin.dll, Geta.NotFoundHandler.dll, and Geta.NotFoundHandler.Optimizely.dll. We are actually only referencing Geta.NotFoundHandler.Optimizely nuget package and nuget pulls the others in automatically for us.

The NotFoundHandler works locally when run from Visual Studio without issue.

I have verified that the following DLLs are being deployed in the artifact produced by our build pipeline which targets .net8.0:
Geta.NotFoundHandler.Admin.dll
Geta.NotFoundHandler.dll
Geta.NotFoundHandler.Optimizely.dll

I have also verified that modules/_protected/Geta.NotFoundHandler.Optimizely/module.config is being deployed in our artifact as well.

Pertinent Startup.cs code:
From ConfigureServices method:
services.AddNotFoundHandler(o =>
{
o.UseSqlServer(_dbConnectionsString);
o.Logging = LoggerMode.On;
}, policy =>
{
policy.RequireRole(EPiServer.Authorization.Roles.WebAdmins);
});
services.AddOptimizelyNotFoundHandler();

From Configure method:
app.UseNotFoundHandler();
app.UseOptimizelyNotFoundHandler();

Any assistance that could be provided would be appreciated.
