Error loading AjaxControlToolkit v20.1.0 on mojoPortal with .NET 4.8

Hello, I am trying to use the AjaxControlToolkit Editor control on my mojoPortal site, which runs on .NET Framework 4.8.

I have installed AjaxControlToolkit (version 20.1.0) via NuGet. The DLL is in the /bin folder and my web.config has the correct <assemblies> and <controls> entries.

However, I constantly get the compilation error: "Could not load file or assembly 'AjaxControlToolkit' or one of its dependencies. The specified file cannot be found."

This error happens even on a completely new, blank .aspx page, so it's a site-wide configuration problem. I have already cleared all ASP.NET caches.

Is there a known conflict or a special procedure to integrate the modern AjaxControlToolkit with a mojoPortal installation?

Thank you.
