Steps to reproduce:
Search for an obscure query (uncommon combinations of nouns or obscure places worked well for me) and immediately click through to images.
Images to be found.
Firefox on MacOS Monterey, International region setting, connected to EUROPE-WEST.
The bug doesn't seem to be reproducible if there is a delay between searching the query and clicking the images button -- when I tried to clear browser/network consoles prior to clicking I was unable to reproduce it. Attached is a video of the bug reproduced, as well as a screenshot the aforementioned consoles.
Refreshing the page fixes it and displays images properly, as shown in the video.
