AFT8 version 2023.7.21 is a service release for AFT8 version 2023.7.20.
Bug Fix for System.IO.FileNotFoundException
Error: System.IO.FileNotFoundException: Could not load file or assembly ‘System.Text.Json’.
The technical reason is that some PCs were lacking resources required for .NET Standard, so parts of 2023.7.20 had to be rolled back to use backwards-compatible .NET 4.8 serialization legacy technology, Newtonsoft.
Therefore, a missing file error was logged and prevented licensing from being read and applied. Error trace: Error: System.IO.FileNotFoundException: Could not load file or assembly ‘System.Text.Json, Version=7.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51’ or one of its dependencies. The system cannot find the file specified.
Apologies to those affected. It was tested on various desktops and servers and only had issues on some, hence why it slipped through the net. Lesson learned and noted so we can avoid similar issues with modern and legacy technology.
