I would imagine that the IServiceProvider implementation may have been used in a using statement inadvertently somewhere or been disposed outright.

To test if this is the case you could try to resolve the IHttpContextAccessor right after, or in, the ConfigureServices method.

If it resolves there you would need to step through to find out where the IServiceProvider is being disposed.
