I’ve noticed lately that Idea has been freezing during metadata retrieve. I cannot find any other complaints of this, so it may just be me? In the attached “Screenshot.png”, you can see the frozen state. Here it freezes immediately upon clicking “Custom”.
A workaround is to delete the entire project, and recreate it. The initial retrieve works without issue - just any subsequent retrieves fail before the required metadata can be selected.
