Exception - Class "AWS\CRT\Auth\StaticCredentialsProvider" not found error

[tallthom]

Running with the latest version of moodle-local_aws and also pulled in the newest SDK zip file from AWS. When configuring moodle-tool_objectfs with my S3 configuration, the exception occurs:

"Exception - Class "AWS\CRT\Auth\StaticCredentialsProvider" not found"

Right before this issue arrived, I completed the recommendation shown in these instructions:

Exception - AWS Common Runtime for PHP is required to use Signature V4A. Please install it using the instructions found at https://github.com/aws/aws-sdk-php/blob/master/CRT_INSTRUCTIONS.md

I was able to install the AWS common runtime for PHP by downloading the source for the module, compiling it, and then enabling it in the PHP settings for the site.

Happening to me, too. I think the problem exists in the awscrt.so, not in this plugin.
