Checked this issue. Is related to this:
https://stackoverflow.com/questions/51724649/mime-type-of-file-returning-empty-in-javascript-on-some-machines

The only solution I see, as we are not going to add a key on windows registry, is to also accept empty file type '' as valid and rely in all other validations

I have no issues with the csv's I've been using. Maybe there is something specific about that .csv file
