Alignment disappeared suddenly with training more

The model was attending properly at 11k steps of training. The alignment kept improving from 8k to 11k. After that, suddenly the alignment got destroyed at 12k and is continuously destroyed till 49k. I did not train after that.

Here is a pic for the alignment at 11k

I am currently using those hyper-parameters

num_freq=2050, sample_rate=48000,

How do you make this alignment chart?

It automatically gets created as the NN is being trained
