Can't Open Snapchats - Black Screen Issue and No Loading

I am having trouble viewing Snapchats because they just show up as a black screen and will not load. This problem also applies to videos and memories. I have attempted various troubleshooting methods, such as clearing the cache and resetting all settings, but unfortunately, the issue continues to persist.

Could someone lend a hand in explaining the reason behind this occurrence and provide guidance on how to address it? I would greatly appreciate some guidance on the possible causes of this issue and any potential solutions that could be explored.
