This is weird since the entire game is dense with debug savepoints (some save points I didn't get to disable outside of playtest). With that, I can't intuitively tell which cutscene you may have had that issue.
I think it may have been the first "forced" save point where you go to the safehouse of sorts.
If you haven't heard other reports along these lines, I wouldn't invest too much time investigating since this is RM after all and it could have been a fluke nw.js crash or whatever.
