For those getting an error message after updating, I seem to have found a solution. You have to completely uninstall the old version and quit SketchUp, before installing the latest version.
In the past, installing without removing the old version would usually replace the old version. It seems this is not the case in this example. 2.3a works for me now.

Hello, experiencing the same problem here since this morning. Updated the plugin, made sure the requirements are met too, sadly to no avail. Does anyone know what the problem may be?

Hello, experiencing the same issue here. Updated to the latest version and now can't start the plugin. Made sure the requirements are updated and working. Would be thankful for a quick feedback!
