Watfs fails with "could not determine file system attributes"

In an existing project, I started experiencing the following error. The stack occurs after the Build Successful notice. A clean project does not have the same problem.

I’ve tried clearing caches, etc. Doesn’t help.

Sounds to me like you should open an issue ticket about it if there is none yet. :slight_smile:
