Just updated to the latest SDK (2.111.210802), using Unity 2020.3.14, and now seeing this warning spammed in console if I try to look at 'Settings' in the editor extension. Impossible to change settings through the editor extension like this, can still change them by using the Inspector to look at the settings SO.
The settings still exist, deleting and reinstalling the SDK & extensions also shows the same error.
