The image of the single listing pages is invisible

I have a problem, in the single listing pages, the image is difficult to display. I mean where the image should display remains white. the image is present but invisible. I say that the image is present because when I put the mouse on the area, the mouse turns into a magnifying glass and when I click with the magnifying glass, the image appears in the magnifying glass. sometimes when I refresh the page the image appears but sometimes the image does not appear. before i didn’t have this problem i think it started after the plugin update.
On the listings page, I click on a listing, I am redirected to the single listing pages. on this page should display the image of the listing, but instead of the image I have white, the image is invisible. but when i put the mouse on the white, the mouse turns into a magnifying glass, and when i click with that magnifying glass, the image shows in the magnifying glass but not on the page. sometimes when I refresh the page the image appears but sometimes nothing. thank you for helping me
