5G NR MIB Recovery Using Xilinx RFSoC Device: Segmentation Fault

MATLAB: v2022b
Vivado ML Enterprise Edition: v2020.2
Ubuntu: 20.04 LTS
I am running the https://www.mathworks.com/help/soc/ug/5GNRCellSearchUsingXilinxRFSoCDevice.html example on the Zynq Ultrascale+RFSoC ZCU111.
I am providing 256 as the Burst length on the Software-to-AIX Stream. Followed by Configure, Build & Deploy, during the build process synthesis MATLAB crashes with the following crash report:
EDIT: An important part that I realized maybe important is that my browsers also crash upon MATLABs crash, I'm not exactly sure how this would be relavant but it might suggest memory problems?

I have seen other posts about segmentation fault including:
But I don't see any post that might explain since these are just out-of-the-box examples provided by Matlab inaccordance with Vivado.
Any help is really appreciate!

Hi Danna,
A segmentation fault error typically indicates an attempt to access a restricted memory location. Since you've observed that your browsers crash when MATLAB does, this could suggest a system-wide memory issue. To address this, you can try increasing MATLAB's memory limit using the “ulimit” command in Ubuntu and ensure that your system has enough resources (RAM and CPU) to handle the workload.
Make sure you are using the latest versions of all required software and that your hardware drivers are up to date. If the problem persists, reviewing the Vivado logs, MATLAB crash report, and system logs may provide further insight. Also, you can try rebooting the system after all the updates.
You can refer to the following community answers regarding the segmentation fault:
This should resolve your issue!
