Blocks area did not load properly!

Sounds as though this is related to another Topic of similar issue:

The blocks area did not load properly. Changes to the blocks for screen ?_Screen1 will not be saved

I am having the same issue. I am receiving the blocks didn’t load completely error message for a project that was working without issue yesterday (Feb 3). Creating new projects by importing .aia files created between a month and several days ago result in the same error message.
