It's probably just me, but I noticed how the game tend to crash during dialogues - is this a problem shared amongst others as well?
This sounds a bit unexpected. Which version are you using and what are you playing on? What do you mean by "tend to crash during dialogues"? Does any message appear? Or does the game just close?
Could you please send us in Discord the log file after another crash? It's located in C:\Users[USER_NAME]\AppData\LocalLow\Wild Pear\Magic Academy and named Player.log and Player-prev.log.
