Plots and values (disp) doesn't show up

Last week, MATLAB was working okay and all outputs/plots were showing up just fine. But, a few days ago when I tried to run the same code suddenly the program started acting up and doesn't show any results. This is essential software for my current class, so it is important for MATLAB to work properly. Please help as soon as possible. Any advice is appreciated.

If it is working last week, why do you think it is not working now?

Show us your code. Did you make any changes in the code in due course of time?

Solved my problem. I installed the latest version of MATLAB (2021b). Thanks!
