Another patch.
It seems that an issue with project import still occurs. From version 164.0 I am facing an issue. When I try to open a project from a local file (I am using Chrome on Windows 10) an error message shows up. I haven't sent a report because I thought it could be fixed on minor patches.
I can't see anything wrong with r164.3, it seems to work fine here. As ever if you have trouble please file a bug report following all the guidelines or we can't help.
