Why does opening Simulink for the first time in a MATLAB session take a long time?

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• The driver for the Windows default printer is outdated.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.

what about on Mac? (version R2019a, opening the built-in demo sldemo_absbrake, takes about 30s to start)

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 ...

My MATLAB opens in less than 1 minute but the Simulink has not started in a few minutes. :<

For me it was always slow but bearable, but this morning the loading time is approching eternal.
