Two initial suggestions (probably obvious):
- Drop back to four days while your ankle heals (as perhaps the increase in volume aggravated the condition)
- Catch everything in the power position for now
From there, you can have two different takes: try to find approximate substitutions that strengthen the same areas that are strengthened by the offending exercises, or address weaknesses that contribute to the overall problem. During injury recovery you sometimes have to reorient your goals from fulfilling the exact goals of the program to addressing contributing weaknesses.
The former would be something like using lunges (with shin perpendicular to the floor to minimize dorsiflexion), planks, and general back work for front squats. Not ideal, but better than nothing. The latter would be aggressively addressing a particular weakness in the movement--for instance, if you fail front squats consistently due to weakness in your upper back, now is the time to hit barbell rows/"Zercher back curls"/whatnot hard.
Are you still able to pull from the floor? If so, this opens up a lot of possibilities, especially if your problem is positional strength. Pause pulls/deadlifts (like pausing at the knee, etc) and pulls from blocks, hang, etc can be tremendously helpful for developing positional strength as well as drilling those aspects of the movement.
Granted, these are all ideas for substitutions rather than anything one-to-one. You have to look at the exercises that you can't do, decide for each one whether you lack overall strength in it or if there's an area that's particularly lagging, and make appropriate substitutions.
