How to resolve "Matlab stopped working and needs to close" in MATLAB 2021a.

The following crash log appears when this message pops up. Matlab gets started, I run my simulation once, but when I try to view scope or run it a second time , this messsage gets popped up and closes matlab. I am using Matlab 2021a.The simulation I have been running for past few weeks and worked fine. Recenlty, there were some windows update as well as NVIDIA graphics driver update. I did both but the issue still persists. It began even before I did the updates.

Hi @Prarambhik,

Does this issue happen everytime with you? Have you tried running simulation into different matlab version or OS?
