Hi
today, My computer crashed while calculating, then I restarted it, but after restarting it can't parallelize the calculations, I tested it using the example stokesI under the tut folder, the log file is as follows:

It should be noted that before my computer died, I used the quick reconfiguration method on the forum but may have set too many cores.
