I have added/updated product videos in my Magento 2.3.4. The videos are showing on the admin side. But on the frontend, the videos are not showing. It is not even coming in the slider. It was working earlier. After updating the video URL or adding a new video it is not showing. I have printed the data of $block->getGalleryImagesJson(). In that, there is an image path for the thumbnail, but when I tried that path in the browser it returned a 404 error. So the thumb image for the video is not saving into the cache folder but is showing on the admin side.
