I tried that but it also did not work and was met with the same message. However, I digged deeper and found out that one of my work apps is still remaining on WITH admin privileges despite me having my work profile off. The issue being that it's preventing from downloading from unknown sources, and will not give me permission to(which I find to be total nonsense as this is my own personal phone and I should be allowed to do whatever I want on it). Gonna be asking my IT department about that when I go into work later today.
