Why can't I download images from Discord and Google Chrome and apps from the Play Store?

[Android Central Question]

I've tried everything I can to fix this annoying problem, but nothing seems to be working. Whenever I try to download an app, it always stays at 'download pending...' and when I try to download an image from Google Chrome, the download bar goes all the way to end, but then Chrome closes and the download fails. Same with Discord. I've cleared the data and cache from the Play Store and restarted my phone numerous times. Doesn't fix anything. Can anyone please tell me what I need to do to fix this?
