New Xiaomi 15 Ultra - SIM Network disconnecting

[MonarchGaming]

Hi, a bug on the new xiaomi.eu_XUANYUAN_OS2.0.117.0.VOACNXM_15.zip. I Clean Installed the ROM and initially the SIM card was working without installing the modem_firmware which was needed previously. However, after a couple of minutes the SIM gets disconnected and is only recoverable via a restart + removing the SIM car tray and reinstalling the tray again.
