I got a request for this months ago but couldn't think of a way to bypass the game's protection from debugging. Now that it is out of the way, I managed to create an FOV changer. It is somewhat flawed in that it also affects the character model at the equipment screens, similarly to an early version of my Fallen Order trainer.
I also don't think the game requires an FOV changer, as there is an 'extended FOV' slider from 0 to 100 and a toggle for a close / far camera view. As such, I'm sharing the tool with that user and releasing it here for testing before going public and taking on the burden of maintaining it over updates.
I included the recently released fix for the black bars in the trainer for good measure as well. Both require disabling BattleEye.
