Worker crashed while executing code

Warning: 1 worker(s) crashed while executing code in the current parallel pool. MATLAB may attempt to run the code again on the remaining workers of the pool, unless an spmd block has run. View the crash dump files to determine what caused the workers to crash.

As I have the home licenses I'm not sure what to do with the error above. The script is training a Trebagger model with parallel turned on. It does use a lot of memory but still fits within the 32GB I have. The log is :-

It doesn't always happen but I'd like to know if anyone has an idea why this might be happening and if it affects the training or not.

Please could you contact MathWorks support to help diagnose this. They can help you collect log files from the workers which might give more information as to what's going wrong in this case.

Hi. I have the home version of the licence so don't have support.

I have the same issue
