    Resolution Note (fix version 2021.2):

    Fixed in 2022.1.0a3. You can work around it by changing the Stripping Level option in the Player Settings to "Low". This problem only occurs when that setting is either "Medium" or "High".

    Another workaround for this issue involves adding a link.xml file to the Assets directory of the project with the following contents:

    <linker>
    <assembly fullname="System">
    <type fullname="System.Uri">
    <method signature="System.Void .ctor(System.String)" />
    </type>
    </assembly>
    </linker>
