The cryptic error message is of little help, but the stack trace shows that the error occurs in the line:

Wrap your script with timeout of 3600 seconds (1 hour). Your script time outs with default time = 2 minutes (120 seconds) per command. So,:

As the error message states:

Building the example helped to realize that this answer was in fact enough.
My app had another constraint that I didn't realize before. The Dispatcher was disabled -.-... Thank you sintar for your help!

The end goal is to hide Wi-Fi icon from menu bar.

UI Scripting of System Preferences in macOS Big Sur has become a nightmare, as many of the methods that used to work in previous versions of macOS just no longer do in macOS Big Sur. Many UI elements report Parent does not report element as one of its children when using Accessibility Inspector of Xcode, which then make it impossible to communicate with them. Or some code may work one time and then not the next. I wrote some code that opened to Wi-Fi and clicked the Show in Menu Bar checkbox. It worked a few times and now it doesn't.

The original code I wrote which sporadically worked I'll not post, however, the following example AppleScript code does consistently work as tested under macOS Big Sur 11.4, albeit it is what I consider kludgy UI Scripting, as it's visible on screen, is prone to failure due to timing issues, or if the hierarchical UI element structures change due to macOS updates/upgrades.

The example AppleScript code, shown below, was tested in Script Editor under macOS Big Sur 11.4 with Language & Region settings in System Preferences set to English (US) — Primary and worked for me without issue¹.

• ¹ _{Assumes necessary and appropriate setting in System Preferences > Security & Privacy > Privacy have been set/addressed as needed.}

This script requires that the Use keyboard navigation to move focus between controls checkbox is checked on the System Preferences > Keyboard > Shortcuts tab, and as coded, the script checks its status and toggles the checkbox, as necessary, based on its current status.

This script also first checks to see if the Wi-Fi icon is shown on the Menu Bar and if not, then halt execution of the script, as its purpose is to act only if it is shown on the Menu Bar.

I'm compiling with GL_GLEXT_PROTOTYPES=1.

Well, don't do that. That is never going to work in a portable way. On windows, the opengl32.dll always exports only the functions which are in OpenGL 1.1, and for everything beyond that, you have to rely to the OpenGL extension loading mechanism at runtime.

I have tried:

• [...]
• Adding GLEW

That's a step in the right direction. But this does not make things to magically work. A GL loader like GLEW typically brings its own header as a replacement for GL.h and glext.h etc., and the typical GL loader (like GLEW) simply re-define every GL functions as a macro, like this:

There was an indentation error in my code. I would like to thank @Inclement for his help.

Problem was resolved by this piece of code in AppDelegate

I’m afraid there is no way to make window close to side of the screen. Currently, uwp doesn’t provide such api to support this feature requirement. If you do want this feature, please submit your feature requirement to Windows Feedback Hub app.
