One UI 6 update not able to make phone calls

[vatsag]

I have enabled the option to download automatically the updates in my A53. However ever since the recent update One UI 6, my phone has started behaving weird. Sometimes I am not able to make phone calls. The internet stops working all of sudden. Is anyone facing such issues ? What is the possible resolution and any hotfix is planned ?
