Error When Saving GIFs: "Error initializing complex filters: Invalid argument"

[Foadsf]

Following this question on Discord, I've encountered an issue with ShareX on Windows 10 when attempting to save screen recordings as GIFs. Each attempt results in an FFmpeg-related error, preventing the GIF from being saved correctly. The problem might be linked to the configuration of the complex filters in FFmpeg, particularly around audio stream mixing. Below is the error message received:
