S3 access denied error for a mediaconvert job

Question

I am trying to follow the instructions from this AWS documentation to create a AWS MediaConvert job with a KMS key for server side encryption https://docs.aws.amazon.com/mediaconvert/latest/ug/implementing-server-side-encryption.html

The job keeps giving me error
Unable to write to output file [s3://{path to my output bucket}/file_example_MP4_480_1_5MGhls_264_00001.ts]: [Failed to write data: Access Denied]

I understand that the job is unable to access the output bucket. I have tried everything but nothing seems to work.

Here are some of the links I referred
What permissions S3 needs for AWS MediaConverter to have access to write files? https://repost.aws/questions/QUWX3fYP2CT7eychPQqiwHJQ/unable-to-write-to-output-file

Here is my policy snapshot for my Media Converter Role Mediaconvert_default_role_* policy

Can someone help me troubleshoot the issue? Any help is appreciated. Thanks
