StrykerJS gets access denied when scanning project workspace on files used by Docker container

Summary

I'm attempting to configure StrykerJS in my work's application as a proof-of-concept to validate our existing unit test suite. Currently, we use Docker images to host the backend database and RabbitMQ instances, with the data files stored inside a directory within the project (ignored by Git, of course). I've marked the directory to be ignored by StrykerJS, but when I run Stryker via npx stryker run it returns the following error message:

15:14:41 (1169) INFO ConfigReader Using stryker.conf.json

15:14:49 (1169) INFO Stryker Still having trouble figuring out what went wrong? Try `npx stryker run --fileLogLevel trace --logLevel debug` to get some more info.

This is with Stryker version 5.6.1; our app is currently limited to using NodeJS 14.15, so we're currently unable to use the latest version of Stryker.
