My S22 now doesn't see my sim card (which works in other phones, so know this this fine) and i keep getting error messages:

com.android.phone keeps stopping

Samsung members  app gives error 'keeps stopping' (so can't open this)

last software update was 19th June (even though auto updates on?)

SIM manager won't open (just blue dots whirring) - and SIM1 now 'unknown'

SIM manager previously was showing SIM2 for my nano sim but I reset network settings to try and remove error on start up which was always saying 'sim not found' - SIM worked after this but on 2nd restart it couldn't see SIM and none of the samsung software seems to work? 

I have hard reset and not sure what else to do now, other than factory reset?
