You could probably try a hard reset. It's suggested ideally, anyways, to do a reset after a major update to get rid of possible bugs.

Also please clear the cache after the reset.

Dear brother, this problem I faced also in my A51 and M21 after previous month update and fixed that easily by reset settings
follow these steps...

"Goto settings > general management > reset > reset all settings "
after reset it will restart automatically. And your settings will be default and new 👌
It's very safe and no any type of data loosing... 👍

If you find this helpful then accept this solution brother by clicking on three dots.. 👍 take care 🙂

Hi,
It might be an off-topic question, but are you able to see the Sim application (like airtel live) for your eSim?
I guess there is an issue after the update as I am not able to see it. I did reset the phone as well.
