This is correct, SketchUp upgraded to Ruby 2.7 in SU 2021. This means that versions of OpenStudio based on Ruby 2.5 (https://github.com/NREL/OpenStudio/wi...) are not compatible with SU 2021. Coincidently, there is an enhancement request (https://github.com/NREL/OpenStudio/is...) to update OpenStudio to Ruby 2.7 which would resolve allow the next version of the OpenStudio SketchUp Plug-in and OpenStudio Application (which are built on top of OpenStudio) to be compatible with SU 2021. Updating OpenStudio to Ruby 2.7 would provide other benefits as well such as compatibility with Ubuntu 20.04. The Ruby community is moving quickly towards 3.0 right now and many gems are aggressively updating their minimum versions, updating OpenStudio to Ruby 2.7 would allow use of those gems as well.
In the meantime, you should be able to continue to use SU 2020 with the OpenStudio SketchUp Plug-in and OpenStudio Application 1.1.0.
Thank you very much for advising me as to the situation. Roger Larson
A release candidate OpenStudio Application v1.2.0-RC1 is available at the link below. This RC includes OpenStudio SDK 3.2.0. It updates to EnergyPlus v9.5.0, Ruby 2.7.2, and is compatible with SketchUp 2021.
