If untill now you are still running with the same issue, let me hope your what app is updated ,app cache cleared,your files are not corrupted, your file formats you are trying to share are supported, if you don't see specific photos or videos from specific contacts, you turned the media visibility to *default(yes)* and also try force stopping the app and also restart the mobile
As at 28-12-24, with the December update on my system, this bug has been patched. It may have been patched before then, but it has been fixed now.
So, feel free to enable Autoblocker, with Maximum restrictions also enabled, and you'll still be able to easily share images from the Samsung Gallery app.
