Hi Joshitha,
This issue sometimes occurs due to a missing GTK module on the system. The official MATLAB documentation provides a solution for Red Hat and Debian-based systems:
However, on Manjaro or other Arch-based systems, you can install the required module using:
sudo pacman -S libcanberra
If the warning still appears after installation, you might also need to set the GTK_PATH environment variable to point to the appropriate GTK module lib path.
You can also find more context in the following MATLAB Answers thread:
