Stuck "snapshotting"

I have a Windows VM and I wanted to upgrade it and to do so followed the instructions here: https://lightsail.aws.amazon.com/ls/docs/en_us/articles/prepare-windows-based-instance-and-create-snapshot

However, it's been stuck for over an hour saying "Snapshotting..." - I don't know what I can do at this point to get it working again. If I try to start the instance it says "You cannot start an instance while it is in transition."
