This is very likely a corrupt transform cache entry, particularly seeing that you're using Windows. Metro's file cache serves a zero-prefixed file as a valid hit, and when we deserialise that null the
dependenciesaccess is the first error we hit. On Windows an all-zeroes file is exactly what NTFS can leave behind with a crash or power loss mid-write.Tracking that specific issue in #1961, so closing this one (apologies it didn't get a response at the time).
For anyone else in the meantime,
--reset-cache(or clearing%TEMP%\metro-cache) should get you unstuck.dependencies is not iterable/Cannot read property 'reduce' of undefined:FileStoreserves zero-prefixed cache files as hits #1961
