s3-crt: Crash when calling PutObjectAsync without context

Describe the bug

We are encountering a segmentation fault when calling the PutObjectAsync method in the s3-crt client. The issue specifically occurs when the Aws::Client::AsyncCallerContext parameter is not provided.

This issue did not occur with previous versions of the AWS SDK, suggesting a possible regression. Based on the timing, the problem may be linked to changes introduced in https://github.com/aws/aws-sdk-cpp/issues/3138.

Regression Issue

[X] Select this option if this issue appears to be a regression.

Expected Behavior

The program should execute without crashing, even when PutObjectAsync is called without an AsyncCallerContext.

Current Behavior

The program crashes with a segmentation fault.
