How to reproduce:

1. Open the user attached project
2. Build addressables by going to Window > Asset Management > Addressables > Groups > Build > New Build > Default Build Script
3. Change the Addressables Play Mode Script to Use the Existing Build
4. Open the SampleScene
5. Enter Play Mode

Expected result: there should be no exception (if you set up a server), or the exception should be “RemoteProviderException : Unable to load asset bundle from : http://myhost.com/myFolder/StandaloneWindows64/…”
Actual result: the Console throws “System.UriFormatException: Invalid URI: The hostname could not be parsed.”

Reproducible with: 1.20.3 (2020.3.36f1, 2021.3.6f1, 2022.1.9f1, 2022.2.0a19, 2023.1.0a2)

Reproduced on: Windows 10 (Intel)

Note: uncomment the code from the IDTransformer and it works as expected
