Flaking on First Date, after Only Green flags?

I have been talking to a guy everyday for about 2 months (we matched on dating app). He travels a lot for his full time job and is also a full time student, me being a grad student as well our schedules are all over the place.

However, we were finally supposed to have our first date last week, and he had to cancel last minute. He asked me for a different day to see me the following week. The day of, we still hadn’t really confirmed so I sent him a follow up asking about if he had a time in mind, but I never heard from him. It has been 4 days of silence now.. I was really sad and disappointed because this is so out of character. He has shown nothing but green flags and then all of a sudden disappears when he was the one to ask me out. I don’t understand. I also sent him a message today expressing my disappointment, and he didn’t say anything.
