The error says:
Unable to detach root volume 'vol-0a75b01a93b9e6778' from instance
'i-065d2c70867a8f874'

Which makes sense.

Checking on https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-detaching-volume.html:

"If an EBS volume is the root device of an instance, you must stop the
instance before you can detach the volume."

So, try stopping the instance first?
