Camera Jumps around when I pause my game after updating to Unity 2020.1.1f1

We recently updated Unity to 2020.1.1f1 to see if it would cause any bugs, and it seems that pausing our game now causes the camera to "jump" while in the pause menu. Normally it follows the player with a fairly standard Cinemachine setup with a deadzone. When I say it "jumps", I mean that the camera is normally following the player, and then when we press Esc to pause, it moves the main camera down to be centered on an area below the player. Unpausing re-centers on the player, so it's not that it breaks the function of the game, but it's still not a desirable effect.

For more info, when we bring the pause menu up, we do set the timeScale to 0. Not sure if that's useful for any responses.

Does anyone have any idea why this could be happening? Thanks for any help.
