winerror 2 the system cannot find the file specified when runnning aws sts get-caller-identity

[hacidiq]

I encounter a "winerror 2 the system cannot find the file specified" issue when attempting to execute the sts get-caller-identity command with AWS CLI version 2 using the local administrator account. Surprisingly, when I log in via RDP using a domain account on the same EC2 Windows instance, the command executes without any errors. I have tried to reinstall CLI, Python to the latest versions and environmental variables path is fine - Any lead ?
