Docker on Windows - error when running container

[lylesimpson1989]

I have run into a problem running Neo4j version 4.0.4 on Windows, using Docker Desktop with WSL2.

Everything was fine until a few days ago - now, when running the container (either via docker run or docker-compose up), I get the following error:

2020-08-15 08:14:51.371+0000 INFO  Neo4j Server shutdown initiated by request

I understand that this is a permission error, where Neo4j doesn't seem to have permissions to write to its data directory, but I'm wondering if anybody can help me...

1. How do I fix this issue?
2. What has caused it? The exact same setup worked perfectly for about a month previously.

Thank you for any help provided.
