Asian languages for me, I think...
And those that require tonal inflections...
Yes this! So I was a double major in college: Politics and East Asian Studies and I took a few years of Chinese and also spent a summer in China studying the language. My ex is also Chinese. Since this was way before I was diagnosed, I had no clue why I was having such difficulty, but Chinese is way up there near the top for English and most Germanic and Romance language native speakers (can't speak for others like Slavic languages). Mandarin has four tones which lead to the same syllable meaning four different words depending on the tone. And of course you have to learn at least around 2,000 characters to become proficient/fluent. There is a logical system to how you classify them, but yes it's still complicated.
Japanese is also very difficult partly b/c it uses 3 or 4 different writing systems (including Chinese characters) and the syntax of its words is kind of the opposite of English (Subject +Verb + Object).
Korean and some others are supposed to be alot easier. But some of the Southeast Asian ones are also tonal (Vietnamese, Thai and others).
I've been told Arabic is also fairly difficult, though I don't know enough to say how.
