Thank you for reporting this issue. This is a known bug and we are actively working on fixing it in the course.
In the meantime, the workaround for Task 4 to
  1. Click See Solution (left of the Submit button)
  2. Copy the entire solution from the solution script into the working script
  3. Submit Task 4
If that doesn't work, copy and paste the following code for Task 4:
% Find local maxima
maxIndices = islocalmax(pwr,"SamplePoints",t);
% Display results
figure
plot(t,pwr,"Color",[77 190 238]/255,"DisplayName","Input data")
hold on
% Plot local maxima
plot(t(maxIndices),pwr(maxIndices),"^","Color",[217 83 25]/255,...
"MarkerFaceColor",[217 83 25]/255,"DisplayName","Local maxima")
title("Number of extrema: " + nnz(maxIndices))
hold off
legend
xlabel("t")
Then in Task 5, Reset the script (left of the Submit button) and complete Task 5 normally.
