Simulink outputs variables but they are not being sent to the workspace.

While using my PC at home I am using 'to workspace' blocks in my diagram with save format array. When I run the simulation i get the following the the command window:
ans =
Simulink.SimulationOutput:
Vin: [2002x1 double]
Vout: [2002x1 double]
t: [2002x1 double]
tout: [2002x1 double]
SimulationMetadata: [1x1 Simulink.SimulationMetadata]
ErrorMessage: [0x0 char]
Undefined function or variable 't'.
Error in P1_2 (line 79)
plot(t,Vin,t,Vout)
It seems to me that simulink is outputting the variables but they are not appearing in the workspace and therefore it thinks they are undefined. I tried running the simulation on a computer at my university and it worked. I tried reinstalling Matlab on my home PC and it still doesnt work. Version 2019.

If you are running 2019a, the Simulink default settings for the "To Workspace" block have been changed and would need to be set back from being a single simulation output:

I have to do this every time I make a new model till further notice

First of all, you have to assign a structure Simulink.SimulationOutput to some variable
temp = Simulink.SimulationOutput;
Next, you need to access field t or Vin of this structure
temp.t
temp.Vin
To use plot you want this
temp = Simulink.SimulationOutput;
plot(temp.t, temp.Vin, temp.t, temp.Vout)
