Trouble with Vitis Model Composer 2023.2! MATLAB R2021b crashes when I want to open the Model Composer Hub component.

Hi everyone, I hope to find you all in a good mood.

I'm a fresh Ubuntu and AMD Vitis user! My OS is Ubuntu 22.04.3 LTS, and my system graphic card is Mesa Intel® UHD Graphics 630 (CFL GT2). Recently I installed AMD Vitis 2023.2 and Matlab R2021b, and I've also checked about the version compatibility, It seems that they are compatible.

I checked this GitHub repository: https://github.com/Xilinx/Vitis_Model_Composer/tree/2023.2/Tutorials/HDL_Library. and I just wanted to get started with the model composer, once it was set up, it got stuck in the HDL code-generating step. So I was forced to close the Matlab window. after that every time I tried to open the Model Composer Hub settings window I encountered this error: Dot indexing is not supported for variables of this type. and in the Matlab command window, the thread of errors comes up like this:

MathWorks::System::IUserException in WebControllerFactory::create(): [Error using matlab.internal.cef.webwindow (line 396)

MATLABWindow application failed to launch. Unable to launch the MATLABWindow application. The exit code was: 127

as you can see in the attached picture:

According to my research in different forums, I tried to launch MATLABWindow from this directory ~/MATLAB/R2021b/bin/glnxa64 this error came up: [0212/032751.828388:ERROR:sandbox_linux.cc(374)] InitializeSandbox() called with multiple threads in process gpu-process.

as you can see in this picture:

Now I just wanna ask if is there anyone who can help me.

Thanks for your attention.

Thank you.

I've checked them before, but it's not the answer to my issue! as I've pointed I want to work with Vitis Model Composer, not System Generator which seems to be an old version of Model Composer.

@Zeinab As per this link Table Vitis 2023.2 Model composer is not officaly supported with MATLAB r2021 try using 2023.1 or below:

I checked this link, https://www.xilinx.com/products/design-tools/vitis/vitis-model-composer.html and I faced with the sentence below:

• MATLAB® tool version support​ : R2021a, R2021b Update 6, R2022a Update 6, R2022b

So it seems that the versions are compatible.

I think my issue is something beyond such a thing, in the Matlab Home tab I tried to check for updates, and again these errors came up!

This might be related to a known MATLAB issue: https://www.mathworks.com/matlabcentral/answers/364551-why-is-matlab-unable-to-run-the-matlabwindow-application-on-linux

If you tried to run MATLABWindow outside of MATLAB and got an error message this is a MATLAB tech support issue.

However if you can successfully run MATLABWindow in MATLAB but still get errors in Model Composer, then it's a Model Composer issue that needs to be taken to AMD/Xilinx tech support team.

Thanks for your answer, also I checked the Crash log and it's better to add this issue to my quotes that crash decoding tells "no sandbox or build area path". do you know anything about this?

[Zeinab]

"If you tried to run MATLABWindow outside of MATLAB and got an error message this is a MATLAB tech support issue. "

And also about this part of your answer, I should say that yes, I got a sandbox error even outside of MATLAB when I try to run MATLABWindow.
