Partial FPS decrease in play scenes

After updating to APEX S21 and playing, the FPS dropped significantly during gameplay, to around 1-8 fps.
It recovered to 150 fps when the overlay was displayed, such as when the bag was open or when the option was pressed.
The behavior on the lobby screen also seemed a bit strange, but it was better than the drop during gameplay, so it was still forgivable.
I was able to play at around 140 fps up until S20, so I think there must have been some kind of error in the update file, but I don't know how to solve it.
Other games can be played without any changes.
