Pre-compiled latest version of JsonAsAsset Plugin from
https://github.com/JsonAsAsset/JsonAsAsset/
Noticed Releases tab is missing UE5.6.1 version so I compiled it myself. You can do it yourself in 5 minutes or just download the zip and extract it inside Plugins directory of your UE Project.
The tab for the plugin has moved to be in the Content Browser and I recommend disabling Cloud Server unless you have a specific use for it.
