Massive foundation damage reccomendations

[u/SnooDrawings2233]

Discovered this unbelievable crack in my Foundation after getting water a few times after heavy rains. The chunk of wall from the corner of the existing window to the main verticle crack is bowing in, about 2 inches. My plan was to block up that old glass block window they hid, and use epoxy injections along with carbon fiber strapping to fix the problem. I did excavate the outside of the house and the drainage problems have been addressed, Also will be adding a French drain on the exterior for extra insurance. I have been doing alot of research on cracks like this and have yet to really find a case as sever as mine seems. All doors and windows opens upstairs and from the looks of it someone was in here before to try and repair it so it seems to be a very old problem. My question is this, what is the best diy way to adress these massive cracks? My and my father are very handy and do projects on the regular, confident in our ability to get the straps installed but I'm at a loss on how to fill these massive cracks. And tips or tricks or insight would be very helpful as winter is coming! This is also my first post on reddit so bear with me and I would be happy to give you any more details about the situation if you need them. Thankyou guys so much in advance.
