stack clean --full fails

[mpilgrem]

For both stack.exe version 2.7.5 and the current version (built at commit 403068f), as follows (on Windows 11 - but I do not think this is a Windows-specific problem, having found a solution):

Perhaps you do not have permission to delete these files or they are in use?

--verbose also includes the following log:

2022-04-15 14:20:57.998144: [debug] Need to delete: ["C:\\Users\\mikep\\Documents\\Code\\Haskell\\cleanTest\\.stack-work\\","C:\\Users\\mikep\\Documents\\Code\\Haskell\\cleanTest\\.stack-work\\"]

which explains why the error message appears twice - the same folder is being listed twice for deletion.

There is no problem in deleting .stack-work in Explorer, so it may be stack clean --full is using the very file it seeks to delete.
