Bad JSON escape sequence: \%. Path 'data.metadata', line 1, position 794.

Describe the bug
When clicking the next button after creating the avatar in the WebView, a bad JSON error occurs and the WebView does not give the app the model URL and can't continue past avatar creation. Tried both signed in and not signed in. Selecting an existing avatar and not editing it seems to work.

To Reproduce

• Build the WebView sample into an Android app and create an avatar.
• Click the next button and the app will not respond.

Expected behavior
The avatar creator should end the avatar creation process and give the avatar URL to the app.

Screenshots

As you can see, the next button is stuck.

Additional context
I was updating the RPM SDK from v1.3.4 to v7.1.1 and encountered this issue. Deleted the old SDK from the package cache, removed the avatarloader package completely and then edited the package manifest to the latest SDK versions. I have not tried recreating the bug in a fresh project, but it has been recreated in the WebView sample.
