Photonic gallery randomly not rendering

Hello, have issue similar to this: https://ww.wp.xz.cn/support/topic/gallery-only-loads-on-window-resize/, however, for me changing to JS rendering does not help.

In fact nothing helps, tried various options and still photonic randomly fails to render. I am using wordpress uploaded photos and Astra theme.

Resizing winow helps. Was trying to disable catche plugins etc, nothing helped.

The page I need help with: [log in to see the link]
