Use Get not Import

This should not be an issue.

When you say Get["file"] doesn't work, what do you mean? Do you
mean there is no apparent output? If so, that is what is
supposed to happen.

Start with a fresh session and do the following:

a = 5;
f[x_]:=x^2

Save["test",{a,f}]

Note that

?Global`*

shows both a and f exist

Now do

Remove[a,f];
?Global`*

you should see both a and f are gone

=46inally, do

Get["test"]
?Global`*

you should see both a and f are back and behave as expected.

If the above doesn't work in a fresh session, then there is a problem.
