My Program Stopped Working After Upgrade To Win11!

Hi! Several years ago, I created a program called Cc65Batch. I use a C compiler called cc65 to code for older computers. It has no IDE. So, I created a program that helps automate the task of creating batch files to compile the code. It also adds options to quickly compile one-part programs from Explorer. When I upgraded to Win11, it stopped working. The options it adds don't appear in the context menu, and, when I double-click the main app., nothing happens. It is supposed to display a dialog box with text boxes for information such as Batch Name, System and Files. The program is at c65 additions - Manage /crossplatform/win32 at SourceForge.net. If you need more information, just ask.
