KNIME Core Extension Nodes missing with version 3.6.2 update

I recently updated to version 3.6.2 and now as a side effect I am missing KNIME Core Extension nodes such as String Manipulation (and a few others).

In my console I see errors including:

ERROR RepositoryManager Node org.knime.base.node.jsnippet.JavaSnippetNodeFactory’ from plugin ‘org.knime.jsnippets’ could not be created: Can’t load factory class for node: org.knime.base.node.jsnippet.JavaSnippetNodeFactory The corresponding plugin bundle could not be activated!

as well as:

ERROR LoadWorkflowRunnable Status: Error: Node “String Manipulation” not available from extension “KNIME Core” (provided by “KNIME AG, Zurich, Switzerland”; plugin “org.knime.jsnippets” is installed)

I’ve tried uninstalling and reinstalling the KNIME Core Extension, but this has not worked. KNIME cannot fully uninstall the Core extension since other software apparently relies on it.

And each time I get the error the KNIME Core Extension is missing, I get a prompt to install but then I get a message that it is already installed.

Any help would be appreciated! Thanks.
