Did you transfer the sim or get an esim?
from what i have been hearing lately i would look at smartswitch being the culprit.

Have you tried removing the SIM, cleaning the contacts with some Isopropyl, drying it, and putting it back in the device? If the SIM is more than a few years old, I would recommend replacing it. If it was an eSIM. Your ESIM might be corrupt.
Smart Switch has definitely caused a lot of issues on Android 13 for Samsung and with other manufacturers that have apps to carry over data from an older device to a newer one. App data for older apps on a different version of the OS do not mix well. App versions for older versions of Android might not be compatible directly with Android 13. That is why it is always best to back up your data manually and restore it manually.
