Stuck at a package not bound error in the accelerated UVM course

I have been doing the Cadence Accelerated UVM with UVM 1.1 course and I am stuck at the part where you connect your testbench to the DUT. I keep getting a package not bound error even though I have compiled the package before simulation. I have attached the EDA playground of the code and the error message below. Can someone help me figure out whats wrong?

xmvlog: *E,EXPENC (yapp_pkg.sv,37|9): Expecting the keyword 'endclass'.
import yapp_pkg::*;
|
xmvlog: *E,NOPBIND (testbench.sv,9|14): Package yapp_pkg could not be bound.
import yapp_pkg::*;

xmvlog: *E,NOPBIND (testbench.sv,9|14): Package yapp_pkg could not be bound.
