FPS Drop, Freezing, Lagging, and Stuttering Issues

Since the day I bought FC26, I've been experiencing sudden FPS drops in the game. Everything works fine in the first half of a match, but in the second half, the FPS drops to 3-5. I've tried everything to fix this problem, but nothing has changed. Please find a solution to this issue. I can't experience the game properly, and my money is going to waste.
