How do I get git stash after updating my MM?

[DæmonEyes]

So I learned after the last update that updating MM will reset all the default modules to their default code. (I had edited my compliments). So I got advised by a user here to do a git stash.
But after updating my MM, I can’t get my stash to merge or apply.
I’ve attached pics to show what all I’ve tried.

@DæmonEyes I think it is

 git stash pop

And I think u can do individual files
