Got the same issue on a new docker container.

[vitobotta]

Found a temporary workaround: I ran

docker exec -it firefly composer require bacon/bacon-qr-code 1.0.3

to revert the version of the relevant library (found the tip somewhere). It's needed only once to produce the QR code so you can scan with the mobile app and enable the 2FA.

Following that destroying and recreating the container doesn't matter because the QR code thing is no longer needed.

[JC5]

This will be fixed in the next release. Thanks for notifying me.
