No sim card detected, no imei, sim card manager crashes

[wellingtonboots]

I have a Samsung galaxy s10 SM-G973F, android version 9 kernel version 4.14.85-17063867 

I suddenly stopped being able to receive calls, even though I could make calls, I still has full signal bars. I restarted my phone and there was no sim cards detected, no signal. 

I tired to open sim card manager in settings but it showed only a blank black screen - and then an error messasge com.android.phone has stopped working. 

I looked in about phone - and the IMEI information was all unknown despite previously having been there. 

I am still able to connect to wifi, bluetooth etc. My samsung account still connects. 

I have already tried:

-removing and replacing two different sim card (which work perfectly in my samsung S6 tablet)

-using a new sim card (which again works in other phones)

-Resetting network connection settings

-Wiping partition (multiple times)

-Booting into safe mode - no difference 

-Factory resetting the phone - no difference. 

I notice that this same problem occured in many Note 8s after a July 2020 update and it was a samsung software issue. There is fix for this issue but only for the Note 8.

However there isn't a recovery for S10,

Please can someone help me with this issue? Is there some way of recovering my phone.

I am experiencing the exact same problem since late October with my S10 5G. After bringing it to Samsung Repair Service, trying to change firmware, all no luck! I also noticed that the Note 8 experienced something like this exactly. Please help! It's January and I still have essentially a useless phone.
