Was working fine with Android 12, now it updated and needs more intrusive files permissions to do anything including opening settings. Response to developer: your quoted website links to Google's answer that clearly states asking for All file access, for the purpose of media file access, is an invalid use of the permission. MX player's core use is to play media. That's all. Not subtitles or managing files, if I want that, then I'll give permission. Don't force it.
