Hangs on boot (Genshin Impact)

Hello. I play on my phone (samsung galaxy s10 +) From today (March 23), Genshin stopped running. Hangs after opening the door in the main menu. White screen. After a couple of minutes, a notification appears that the application is not responding. If you press "wait", then it keeps hanging. I saw today an update in the play market for 50 MB with something. Updated but nothing changed. I also tried to delete and download it again. What could be the problem?
