Exception thrown in synchronous call "bleeds over" to asynchronous call

### Describe the bug

We're running a small test suite of things after upgrading our aging S3 client library to this one. One of the things we've done is added asynchronous/parallel uploading with `putObjectAsync`, but our usages of `getObject` only ever fetch one object so we have that synchronous.

If we force a failure condition from `getObject` (such as fetching an object that doesn't exist), the next calls to any Promise-based functions throw a 'ghost' exception of the synchronous call, despite it not relating to any of the promises we're waiting on.

### Expected Behavior

No exception thrown

### Current Behavior

Exceptions thrown. Here's the exception log we're dealing with;

### Reproduction Steps

In our runTask, we're running two separate tasks: one is a get, which tries to get a file into a path it does not have permissions to write to, `test-get-successv2.png`. **This is supposed to fail, and is failing as expected.**

However, the next task is then supposed to do an unrelated `put_many` to paths that, when executed *without the get having run prior*, succeed with no errors. It is only when running with the `get` that the `put_many` then throws exceptions.

Our "get" function is very simple, only running this (with error checking, etc):

`return $this->s3->getObject($params);`

Our `put_many` is a bit more complex, but all it really does is do several `$this->s3->putObjectAsync`'s, puts them in an array, and then `\GuzzleHttp\Promise\Utils::unwrap`'s them. That unwrap is what's throwing the ghost exception from the prior `getObject`.

Note that the paths in the exception were not sent at all to `put_many`.

### Possible Solution

_No response_

### Additional Information/Context

_No response_

### SDK version used

3.275.1

### Environment details (Version of PHP (`php -v`)? OS name and version, etc.)

PHP 8.0, rest should be unrelated
