Running yarn upgrade-interactive --latest:

Updating package.json manually and running yarn install:

It seems to work fine for me. Might be something with your specific packages and options? Could you try adding --verbose flag too and see if that gives any indication of what it's doing?
I've got the same issue (even without --latest) in three different Windows 10 pc. I think it's a node 10 incompatibility issue.
It's has been already reported in https://github.com/yarnpkg/yarn/issues/6367
@rally25rs what version of node do you have on your computer?
Same here.
Running on Node 10.13
I see there are a lot of people and issue about this, some event 2-3 months old:
I tried node 10.1 and 10.13 on OSX and didn't have any problems. Might just be a Windows + node 10 specific issue? Unfortunately I don't have my Windows machine with me today to try that out. If someone who can consistently reproduce this could help debug, that would be awesome!
