That said: Something is definitely wrong in that screen shot. The icons in the toolbar are wrong for 2.3.2.
My guess is that you have multiple versions installed and they are fighting each other.
Uninstall the plugin, remove all versions of the Blender pipeline plugin from the OpenPlugin folder, then re-install the plug-in.
Better yet: Re-install the 2.3.4 preview. There’s quite a lot of fixes in that.
