python_on_whales.exceptions.DockerException: [...] The process cannot access the file because it is being used by another process

I am trying to get UC Berkeley's otter-grader (python package that uses Docker) to work on my local machine:
https://otter-grader.readthedocs.io/en/latest/tutorial.html

I run the following from the command prompt and it seems to work for awhile until I get an error:

otter grade -p submissions\ipynbs -a dist\autograder\demo-autograder_*.zip --pdfs -v

I am using Windows 11.

I have installed Python using Anaconda:

>python --version
Python 3.10.9

I have installed otter-grader into a conda environment called data111 (the name of our course)
I have downloaded and unzipped the tutorial folder.

I open command prompt and ran conda activate data111 and then otter assign demo.ipynb dist and this successfully created the demo folder.

I installed Docker, opened it and logged in. Here is the version info from the command prompt:

In the command prompt I did a wsl --update. I checked the version like this:

>wsl --version
WSL version: 1.2.5.0
Kernel version: 5.15.90.1
WSLg version: 1.0.51
MSRDC version: 1.2.3770

Windows version: 10.0.22621.1702

I have installed Ubuntu. I open Ubuntu and run this command for the version info:

:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 22.04.2 LTS
Release:        22.04
Codename:       jammy

I went to Docker Settings> Resources> WSL Integration. I turned on Enable integration with additional distros for Ubuntu. (I tried it without this too.)

I check what is running:

>wsl -l -v
  NAME                   STATE           VERSION
* Ubuntu                 Running         2
  docker-desktop-data    Running         2
  docker-desktop         Running         2

I have worked with my university IT and gotten administrator privileges and temporarily disabled my anti-virus. I tried uninstalling and reinstalling everything. No luck. IT is also stumped. Please help!

This should be fixed in Otter-Grader v4.4.1.
