Here's a screenshot of a similar formation that I use. You can see from the Team Instructions and Fluidity settings that this is not as defensive a formation as it may appear - although it has proven effective against top teams who play 4-2-3-1 against me, by congesting the area that the three Attacking Midfielders want to occupy and hitting them on the break:

The first thing that strikes me about your formation is that your players are arranged in straight lines. With the exception of the Wing-Backs, the defenders defend, the midfielders support and the attackers attack. Your team doesn't appear to be trying to break the lines of the opposition's formation - to draw defensive players out to make space for through balls and attacking runs from deep.
In my version, the Left-Back attacks while the Inside Forward is on Support duty, moving infield to create space for the overlap. The Right-Back is more restrained with Support duty and the Right Winger attacks the byline.
I've got a Ball-Winning Midfielder alongside a Deep-Lying Playmaker in the DM positions, encouraging the latter to push up a bit more while the former looks after everything at the back. That might work better if the BWM was on the left of the two to cover the Left-Back; I might change that. Having just read the Regista description, that might be even better than a DLP, so worth experimenting.

If Mateo Kovacic is as good in your game as he appears to be in mine (now in 2024/25), then I'd encourage you to pull him into the M_C position as an Advanced Forward_Attack with instructions to play More Direct Passes and Roam From Position (he will automatically Dribble More). This is one of his preferred positions/roles and by picking the ball up in deeper positions he will be able to run at the opposition defence at pace, causing them to commit themselves by coming out of position, giving away fouls and allowing space in behind them to play-in attacking team-mates.
Ishak Belfodil is 6ft4in and a good all-round Striker, so Complete Forward_Support (or possibly Target Man_Support) should be ideal for him. Crosses from the byline from the right winger and from deep by the left back - aimed at Target Man - should provide plenty of opportunities. By acting in the support role, he will automatically be instructed to Hold The Ball Up, making him available to play short through balls and one-twos with Kovacic and your IF and/or Winger to play them in on-goal through the middle and in the channels.
Short passing and possession football helps to bring the full-backs up to join in the passing move and provide additional width. Central midfielders who list Like To Switch Play To Opposite Flank and/or Tries Long Range Passes Often among their Preferred Moves should be instructed to play More Direct Passes so they can exploit open spaces, as-and-when they occur, to release your wingers and take advantage of counter attacking opportunities.
