RL training abruptly stops after 6 episodes

I've tried multiple times till now. I'm using TRPO agent for training and everytime the training stops after 6 episodes. Then I have to manually resume the training over and over. Moreover, the reward of each episode starts decreasing after 6th episode. I anyone can provide a sloution to this I'll greatly appreciate.

There is likely some error on the environment side that you need to find. Maybe the simulation reaches a state that triggers an error, leading the training to stop.
