PermissionError with spacy train on Windows - spacy

Question

This question is same as asked in this GitHub discussion.
I am using the latest version (3.3.0).
This has also been discussed before: this previous discussion.
While training, I am facing errors like PermissionError: [WinError 5] Access is denied: 'output\\model-best\\ner'.
I am using the following line as mentioned in the earlier discussion (link above)
python -m spacy init config config.cfg --lang en --pipeline ner --force
(python -m spacy init fill-config base_config.cfg config.cfg also doesn't work)
Then I am converting some CoNLL 2003 data to spacy format (using spacy convert ... -c ner).
Then trying to train using
python -m spacy train ./config.cfg --output ./output --paths.train <path to train.spacy> --paths.dev <path to valid.spacy>
I am getting the following error:
...lots of lines...
File "C:\Users\username\AppData\Local\Programs\Python\Python39\lib\shutil.py", line 620, in _rmtree_unsafe
os.rmdir(path)
PermissionError: [WinError 5] Access is denied: 'output\\model-best\\ner'
As mentioned in the earlier discussion, I have already tried running
import spacy, shutil
nlp = spacy.blank("en")
print("saving model")
nlp.to_disk("check-serialize")
print("deleting model")
shutil.rmtree("check-serialize")
print("delete finished")
and this works fine.
Using Windows Terminal in admin mode gives similar errors.
The config file can be found at the 1st link above.
