Hello!
Grub 2.06 is now available in the candidate stream https://images.maas.io/ephemeral-v3/candidate/bootloaders/uefi/amd64/20230203.0/
Can you please check if the new version fixes the issue?
In order to test the candidate, you need to change the stream, here is the doc to help you.
Once it’s confirmed that it works for you, we can promote a new image to the stable.
