Unknown folder permission issue question

What I’m working on is the following link:

I’m using a virtual environment and my python version is 3.7.
The package was installed successfully.
I will learn tts of multiple speakers.
However, one folder keeps giving me a permission error. The error message is as follows:
PermissionError: [Errno 13] Permission denied: ‘abc/’
I created two folders.
The two folders contain wav audio files.
These are files that have no problem, except for the number of audio files.
I deleted and recreated the abc folder and changed its name.
But the permission error was not resolved.
I am using Windows 11.
Other folders are reading and writing audio files normally, but only the abc folder keeps getting a permission error.
The strange thing is that when I run train_ms.py in Anaconda, a .pt file like K00016823-BFG23-L1N2D1-E-K0KK-03701251.spec.pt is created.
If a permission error occurred, the .pt file should not have been created.
However, the .pt file was created while the permission error occurred.
Isn’t that strange?
