Overwatch 2 Beta (Xbox): UI disappears after Kill Cam

This issue has occurred several times while playing, at least once per round, give or take. All elements of the UI disappear: hero icon, health status, username, ultimate meter, ability icons, weapon and ammo readout, killfeed, even the “Hold X To change hero” notification in the spawn room. It also prevents me from pulling up the score screen. Will sometimes resolve itself, but not always.
