5G stopped working after iOS update

After the update to iOS 16.4.1, my 5G connection has stopped working. I have tried all the recommended steps to resolve the issue, including resetting my device, resetting network settings, updating my carrier settings, and more, but I have not been able to get 5G to work again. It is possible that this is a bug in the latest iOS version and Apple may need to release another update to fix the issue.

I am using an eSIM card and everything was perfect before this update.

My carrier has conducted hundreds of tests to try and resolve this issue, but with no luck.

Interestingly, the physical SIM card is working fine in 5G network, yet the eSIM is not. It only shows LTE.

Please do not suggest any trivial methods like turning on 5G in the settings, as I have tried all such possible solutions in the past two weeks, having done all the research and taken all the necessary steps from my side and the carrier's side.
