Windows Smart App Control blocks anything and everything I do but Windows Security is a black screen.

I received a new laptop recently and it runs windows 11, Smart App Control has block every and ANY download I try immediately marking it as "Malware" or "unsafe" even apps downloaded straight from the Microsoft store. I cant download documents for class or any fixes google recommends. this is my last resort. every code, update or anything I've tried either didn't work or is BLOCKED. My frustration is beyond the point of being able to feel bliss until this issue is resolved. if anyone has an answer please help.

NOTE: Laptop Is DELL and Runs Windows11 also it wont update or repair issues because even though it runs windows 11 it cant repair it I guess?? I'm trying to find a solution that wont cost repair time as well.
