When trying to load/import/read an MPL file with Maple 2023, I get an error message of "Error, recursive assignment" which only links to a page which states "There is no help page available for this error."

Presumably there is an error in the Maple syntax that prevents execution, but I cannot find a way to debug.  Maple Code Editor Diagnostics says "No Errors" but Maple Code Editor Console says "Error: recursive assignment."  The MPL file is 485 lines but I am assuming the error could be anywhere in the file.  Is there any way to fix this?

Update: I found the error by copying just a handful of lines at a time into Maple until the error was reproduced.  It was a typo of just one character out of 16,960 characters.  But this is very frustrating.  Why can't Maple 2023 tell me what line the error is on?  Is there a better way to debug MPL files?

There appears to be a bug in Maple 2023.0 (Build ID 1689885)  that does not allow you to access submenus when the window is maximized.  For example, trying to select "Insert --> Execution Group" does not work, nor does any other submenu (the submenu will not display and is not accessible).  The only workaround is to un-maximize the window, select the submenu (for example "Insert --> Execution Group --> Before Cursor"), and then re-maximize the window.  Everything works as it should as long as the window is not maximized.  This is on Microsoft Windows 11 with a 2160p monitor.  Any suggestions on how to fix this are appreciated.

From the Maple 2023 user manual for AudioTools, when I attempt to input:

with(AudioTools):
Tone := f -> Play(Create(x -> evalhf(sin(1/22050*x*Pi*f)), duration = 1)):
Tone(440);

I get the following error message:

Error, (in DocumentTools:-GetProperty) Attempted to retrieve property of unknown component Speaker0.

Clicking the error message in Maple then goes to this page:

https://www.maplesoft.com/support/help/errors/view.aspx?path=Error,%20(in%20DocumentTools:-GetProperty)%20Attempted%20to%20retrieve%20property%20of%20unknown%20component%20Speaker0.

How do I get a function to play as an audio file in Maple 2023?

Is there a way to enclose in parentheses or brackets a highlighted selection of Maple Input?  This is a nice feature on WXMaxima to quickly and accurately enclose any selection of input syntax in parentheses or brackets.  Otherwise it can become tricky to add the opening and closing parentheses/brackets separately.

How do I insert an Input Prompt (">")?

On Maple 2023, each new input is marked on the right-hand side as (1), (2), (3), etc.  This is equivalent on WXMaxima as %i1, %i2, %i3, etc.  On WXMaxima, I can left-click between any two previous inputs to insert a new input, for example %i4 might be between %i1 and %i2 if I added %i4 after %i3.  However, I can't seem to do this on Maple.  Is there a way to go back and add a new input between two previous inputs on Maple 2023?

Likewise, I can't seem to add a new input prompt after the last input prompt if the last input prompt has not executed.
