Extremely long delay when opening a Simulink model with UDP block (Instrument Control Toolbox)

Hi all,
I have the following problem: When I try to open a Simulink model with an UDP receive or send block (from the Instrument Control Toolbox) for the first time after starting Simulink, I have to wait over 30 minutes until the program show ready. After this first launch, I can work with the model without any problems. The problem still persists after reinstalling Matlab and Simulink. During the startup time, I can see in the task manager that Matlab is using 35 % of the CPU power. There are two processes from type "Java Chromium Embedded Framework (JCEF) Helper" and two from type "Matlab 2020a". I think it is a problem with the "Instrumental Control Toolbox" because I only have this problem when I use blocks from it.
Does someone else also have this problem and how can it be solved?

I have got the same problem after simulation. Since matlab 2020 requires more than 8GB of RAM, the problem must be associated with the RAM. I hope after increasing the RAM of your system, the problem will automatically dissolved

I met the same problem, matlab live scrip .mlx suddently runs very very slow. Open task manager, many processes of Jave Chromium Embedded Framework (JCEF) Helper are listed.
Any suggetions to resovle this problem? Thanks.

I have experienced the same problem with Matlab 2021a
Experimenting with toolbox UMAP, matlab remains iddle as busy (in fact it is "frozen"... and I have to terminate it from task manager) and at the same time the task manager indicates several JCEF Helper processing runnings...
how can resolve this technical issue???
Windows 10 , 16GB Ram...
