Issue with multiprocessing connection while training agent with PPO

I am training my agent with PPO to pack boxes in a bin and since I increased the observation space from 1000 to 10800 and my action space from 100 to 540, the training lasted until the step 508832 and then stop executing the scripts. Before this changes the training lasted 10M steps. My operating system is Windows 10, my python version is 3.8.16, the number of parallel environment is 8,the total number of cores from my computer are 24 and from logic processors are 32 (I don’t know if I am using them apropiately). I got this error message:

global_step=5088032, episodic_return=1.592593
global_step=5088032, episodic_return=0.75

    nread, err = ov.GetOverlappedResult(True)
BrokenPipeError: [WinError 109] Ha terminado la canalización

During handling of the above exception, another exception occurred:

Please could someone explain me what is wrong? why do I get this error? how can I solve it?
