Unable to Delete EBS Snapshot Due to "Currently in Use by AMI" Error

Hello AWS Community,

I'm encountering an issue with deleting an EBS snapshot and seeking advice or solutions from anyone who might have experienced something similar.

I attempted to delete an EBS snapshot from my AWS console, but received the following error message: "[The snapshot is currently in use by ami-1111, including some disabled AMIs.]"

Here are the steps I've taken so far:

I've checked the AMIs section in the EC2 console across all regions to find the AMI mentioned in the error message to deregister it, but there appears to be no such AMI listed under "My AMIs".

I've ensured that my IAM user has permission to view and deregister AMIs.

Given these steps, I'm puzzled as to why I'm still facing this error and unable to delete the snapshot. I'm currently unable to raise a technical support case with AWS Support due to not having a developer support plan.

If anyone here has encountered a similar issue or has insights on potential solutions or workarounds, your input would be greatly appreciated.

Thank you in advance for your help and suggestions!
