Issue with a non-functional button

Thanks to everyone.
Could you please help?
A button has stopped working—strangely, this happened without any action on my part.
I have updated to the latest version, but it still doesn’t work.
I also tried changing the interface, but the problem persists.
I recorded a screen capture of the issue, but I was unable to upload it.
I have, however, taken a screenshot.

Thanks .

Hello @El-Saleh_For_Trading,

Welcome to the forum.

Which on of the buttons here isn’t working?

Also, I can already see that you use Manager Desktop on Windows but I still don’t know your version number.
