Ultimate team lag

(PC) When i load up FC26 my game runs smooth and perfect in the main lobby. When i go on ultimate team my game starts going down to 20FPS and becomes super delayed. This glitch/bug has been with me since day 1 of playing and its super anoying. This video i put here shows how the first 20 seconds shows the game smoothly and then on ultimate team it becomes laggy. Much appreciated if i can get help.
