Regardless of how I open Simulink, when I open it for the first time in a new MATLAB session, it takes almost 15 minutes to open. After the loading process, nothing else in Simulink is slow. How can I speed up this load time?

This is likely due to a known bug related to the default printer being offline:

On Windows, MATLAB appears to stop responding when starting Simulink if either:

The Windows default printer is set to a physical printer and the printer is offline or not available.
The driver for the Windows default printer is outdated.

Simulink starts up after some time.

To workaround this issue, set the Windows default printer to a local printer before starting Simulink, and try updating the driver of the printer to the latest version.

30 seconds? I can spend 5 minutes on windows to open just a new blank in Simulink

I have the same issue, simulink's been about 40 minutes loading... it's the first time, and I have not used yet...so I'm calling this problem "eternal wheel simulink issue"...

I have the R2020a version of Matlab

Did someone solve this?

pd: additionally, MATLAB takes about 15-20 minutes loading ...
