Hi friends. Light Building in 4.23 Freeze the editor with the “Build Status” windows until the light build is ended. No percentage feedback on screen down right as it did before this release. You can check progress through Swarm but can’t do anything until build is done. A really step backward. …

My recommendation is to use the ‘Build Lighting Only’ in the dropdown, this avoids this particular bug which locks the editor in 4.23.
