Martin may have the more correct answer (I haven't tried it).

Note that the 'uparrow' is a math symbol, so (La)TeX expects it to be
in a "math environment". Thus, as a simpler change, to avoid the
error, there are two approaches (the second being the one you want, I
think; but try them both):

ls .[$^$.]*

or

ls .[$\uparrow$.]*
