Is this a known compatibility issue between OpenStudio Application 1.11.1 and this specific SketchUp 2026 build, and if so, is there a fix or newer plug-in build in progress?
There was a change in 2026 26.2.243 which broke compatibility with OpenStudio 1.11.0 and below. As Jospeh pointed out, there are 1.12.0 release candidates available for the OpenStudio Application and Plug-in which address this issue.
The BCL issue was also addressed in 1.12.0 as well as other new features including full internationalization of the OpenStudio Application.

Comment on any issues with the release candidates here:
I have no problems using Sketchup 26.1.256 and plugin 1.12.0-rc. Using older versions from SK or plugin I found problems with the BCL connection
