I also had the same challenge.

You could try https://www.mathworks.com/help/simulink/slref/slcreatetoolstriptab.html

cd('C:\Users\dell\AppData\Roaming\MathWorks\MATLAB\R2021b');
start_simulink
slCreateToolstripComponent("custom");
copyfile( fullfile('resources', 'sl_toolstrip_plugins.json'), '.')

Hi,

I am facing the same error:

>> cd('C:\Users\Heiko\AppData\Roaming\MathWorks\MATLAB\R2021b')
>> start_simulink
Warning: Error parsing file:
	File:
    C:\Users\Heiko\AppData\Roaming\MathWorks\MATLAB\R2021b\sl_toolstrip_plugins\preferences.json

In simulinkrc (line 51)
In Simulink.start_simulink 

After that, Matlab hangs in "Starting Simulink..." state.

Please, can you help me solving this issue?

Best regards,

Heiko

I want you to try the following.

Windows Setting ＞ Network&Internet ＞ Network and Sharing Center ＞

Internet Options ＞ Connections ＞ LAN settings ＞ Uncheck [Bypass proxy server for local addresses]

[Juha Rauhala]

I have alredy uncheked that one. I noticed that the simulink works when I disconnect from internet. I can live with the situation but it would be nice to know what is the problem.
