Tracked it down in sprig to this validate error
1.25.8-eks-ec5523e is a prerelease version and the constraint is only looking for release versions

The following version will match eks's selfreported prerelease versioning >=1.21-0

Yes, semver comparison doesn't match pre-release versions (by default; for the obvious reasons). EKS is (incorrectly?) using -eks-ec5523e to indicate an internal release version. Which is poor/incorrect semver form.

I found the validate calls in sprig to verify the reasons. Above comment is correct, this is a semver for released versions. It's correct in failing the semverCompare
