    Hello Lukas! This error message is related to the Linux Container on Windows (LCOW) feature in Azure Container Instances.<sup>[0]</sup> It occurs when the device mapper is busy and unable to create a new device. To resolve this issue, try restarting the Docker service on the host machine. that doesn't work, try rebooting the host machine.

    Hope it helps to achieve your goal
