After Aetherdrift update: cannot tab out of game without restarting it

Hi guys, maybe one can help: after the last update I cannot tab out of the game (check sms or call) and tab in again later. Game does not resume like before but restarts completely. It's infuriating. I have checked already the battery optimization thing (app -> properties -> battery -> no optimization)
What else can I check or is that an issue everyone has? My device is an Android mobile (Xiaomi 14)
