[BUG] unexpected character "-" in variable name since Docker Desktop 4.35.0

[softwaremaverick]

Description

I've seen this since I upgraded to 4.35.0 today. As a result I couldn't build and therefore uninstalled and re-installed 4.34.3 which worked fine.

The actual segment of the env file looks like this:

DOCKER_HOST=host.docker.internal
aws.sqs.base-url=http://${DOCKER_HOST}:4566/

Steps To Reproduce

1. With this config

DOCKER_HOST=host.docker.internal
aws.sqs.base-url=http://${DOCKER_HOST}:4566/

Hello @softwaremaverick!

This issue will be corrected in the next Docker Desktop release which will have compose version v2.30.0. This issue has been addressed in a previous issue. Sorry for the inconvenience!
