Windows 10: I accidentally messed up Windows Defender (help!)

Hello. I was trying for a method on Youtube to turn off Windows Defender since exclusions was not working, and it kept deleting all my files I need. I did a method where I must of renamed something, I cleared my history so I do not know what the video was. Here is a screenshot of what happeneds when I try to open Windows Defender from the hidden icons. This is an issue since this is causing my PC to not update and I need to update my PC rn, I am on the 2019/07 Cumulative Update Version 1803. It says "Error 0x80070bc9". If anyone can help me get Windows Defender back and so I can update my laptop again? Thanks if you can help, it means a lot. Check out the screenshot when I open Windows Defender. (right after I open Windows Defender, it just closes.)
