This seems to have randomly started a few days ago. It used to be fine to run fish shell from Ubuntu bash for Windows. But suddenly when I hit Tab for autocomplete, it barfs with:
The file "x86" is not executable by this user in command substitution called on standard input
Also, when I just type x86
it doesn't actually run a command, but it tells me:
The file "x86" is not executable by this user
However, which x86
outputs nothing.
Any clue what in the world could be going on here?
