New Launcher crashing on Mi 10 Lite 5G (12.1.2)

[Arthas300]

Hi, I installed MIUI EU ROM like two months ago on my Xiaomi Mi 10 Lite 5G and the last month I've had a really annoying bug.
The bug is that I am using WhatsApp or other applications, and my phone hangs, it goes black for a couple of seconds and it is as if the system launcher would restart.

Thanks!
