FPS PROBLEM 5-10fps

Hello, I bought FC26 about a week ago. In any game mode – Ultimate Team, normal Career mode, Kick-Off – my FPS drops to 5-10 after the second half. When I researched a solution, I found that others experienced this same problem 5 months ago and it still hasn't been fixed. I have an Nvidia RTX 3050Ti graphics card and an Intel i5 11400H processor. Currently, the game is unplayable. I purchased the TOTY version, and when I tried to return it after playing for 70 minutes, you refused my return. I just want to play the game and didn't want to return it. Please fix this problem. I will share an example video; the GPU suddenly reaches 100%. Sometimes, exiting and re-entering Ultimate Team improves the situation, or some users have reported that alt-tabbing the game fixes it. After experiencing this problem, when I completely close the game and start another one, I also encounter FPS drops every 4-5 seconds, so I need to restart my computer. I wanted to mention this as well. Example video: https://www.youtube.com/watch?v=xeUMSQ-b8Zo&t=15s
