When I try to fill this form: http://www.ru.emb-japan.go.jp/VISANDTOURISM/Visa/template/application.pdf -- which is a Visa application form at Japanese embassy in Moscow, Adobe reader DC crashes when I scroll down a Country/Region drop-down list.

I remember that this form have never had such problems in previous years (with earlier version of Acrobat Reader).

I have attached various information that may be useful.
