Cant regain any progress in the gym after breaking my leg

I`m going to the gym a little over two years now. Fist one and a half year my progress was really slow due two eating really little calories. Then in the august I came up with a new diet which was around 3000 calories, 190 g of protein, ~90 g of fats. I started gaining progress really fast. I benched 105 kilos at the end of august and 110 kilos at the end of september. Then I broke my leg and couldn`t go to the gym for entire october. I lost 5 kilos bc wasn`t sticking to my diet that month. After that, in November I started working out again. I regained a lil part of my progress, but than i hit the plateau. I was working out/sleeping/eating EXACTLY the same as before, but this time a had a little to none progress every other gym session. Sometimes i even do less reps than on previous workout. That cant be bc of my organism spending resourses to heal my leg cause my leg is now perfectly fine and I`m gaining weigt, but not on my barbell sadly.
If it matters, Im 19 years old, my height is 185cm and weight is 87 kilos.
For all the freedom units users, its about 6’1 feet and 192 pounds.

Benching relies on leg drive. How much did your lower body lifts drop off from the leg break?

Not that much compared to others somehow, as I said, my leg is perfectly fine now. The problem is with every exercise, even those which don`t really rely on legs
