OpenUTAU crashing more often when using DiffSinger ReFlow models

🐛 Describe the bug

After training a ReFlow model, both acoustic and variance, OpenUTAU tends to crash more often when pitch is being generated for an UST, even though it is a short part. Note that all my models, acoustic, duration and pitch are trained to the maximum amount of steps which is 160.000 steps. I have entered the log file underneath. The crashing happens on both DirectML and CPU use.

Explains how to reproduce the bug

This is mostly for my experience when OpenUTAU is crashing. It always happens when I click the button "generate pitch", and it doesn't matter when it's a big part of a UST or a short part of a UST, it will crash when it takes too long to generate the pitch.
