width and height are not defined

Hello,
when i test my site with Catchpoint, i have this:

Layout shifts exist and may be caused by images missing aspect ratio.

The CLS score is 0.23. 1 layout-critical imageis lacking an aspect ratio, meaning the browser has no way of knowing how tall or wide an image is until it loads. This can cause content to shift as the image loads.

Relevant Experiments

Add Aspect Ratio to Images

This experiment adds width=”…” and height=”…” attributes to specified images, matching their natural width and height, to provide an aspect ratio.

I checked in the code and i notice that the width and the height aren’t defined for this picture…
How can i resolve this?
I noticed too in the source code that the alt is empty alt=” althought i declared it…
And i noticed that it’s the same for the others pictures….

Could you explain me why?

Thanks for your help!
