I loaded your save in the latest version (the unstable branch, accessible via the Steam beta code “latest”) and couldn’t reproduce the issue. The one building in progress in the save was waiting for a Fine window, and once the carpenter crafted it, the building completed correctly. I also tried creating a new building with some furniture and fixtures, and that also built correctly.
Can you try undeploying an anvil? On my last 3 new games for the last 3 updates my anvils have forever sat there never being undeployed…I’ve had to use commands to destroy them every time, even when everyone’s only got hauling on and all the other workshops have been moved they won’t undeploy the anvils. I figure if you’re checking placement maybe you wouldn’t mind checking unplacement too lol.
