Completely disconnected all my Azure Monitor datasources?

My Azure Monitor data sources appear faded/disconnected. When I click on them, all credentials are showing removed and uninitialized. I also get a toast error stating

Plugin not found, no installed plugin with that id

I cannot search for the Azure Monitor plugin from the installed plugins list, however when I attempt to install the Azure Monitor plugin from the Azure gallery, I’m showing the latest version is installed & up to date. What’s going on ?
