According to configure-aws-credentials on each execution a new pair of short-lived credentials are and set as ENVs for the runner

crc-cloud is based on pulumi, and pulumi inherit any standard auth mechanism offered by AWS, also as crc-cloud is being executed within the container we need to pass all the required ENVs to it:

• AWS_DEFAULT_REGION
• AWS_ACCESS_KEY_ID
• AWS_SECRET_ACCESS_KEY
• AWS_SESSION_TOKEN

adding them to the container execution, crc-cloud works as expected (currently failing due to invalida PULL_SECRET content)
