The game keep randomly crashing, then I cant use any character

I get on my guy start flying somewhere with a FP try and open my character window, and boom game crashes, I fly some where on my mount game crashes.... i enter an instance .... game crashes.... i try and hearth.... game crashes lol (its not every time but this has been happening for a few weeks now) I cant get back onto any character until i use the usntuck function on the website... Iv had to reinstall the game 10 times, and use unstuck and wait for 30 min longer because i need to use unstuck again right away because the game crashes again...so mannnny times now its just kinda irritating and im not sure what to do. SO if there is any help i could be given that would be much appreciated.
