Hello @Members_2Cp1hvK
Your phone is closing down or rejecting an update ? > so it could be just a glitch or the phone isn't accepting an update 🤔
I assume all apps and software updates are from the Playstore and the update is from your phone's settings software update section or via SmartSwitch.
I also assume your phone has ample internal storage.
You can clear the phone's System Partition Section via Clear Cache Files from the phone's System Partition Section > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop or use a Tv's USB Port to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too { Possibly excluding the s²⁴ Series of phone's }
And try Safe Mode > https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/ turns off downloaded apps and themes etc which may highlight an app or theme that's causing conflict. Alternatively long press the power off button and then long hold on Turn Off to get to Safe Mode.
A last resort could be to back up and factory reset.
There us a diagnostic test tool found in your Samsung Members App too.
A Samsung Service Centre can assess your phone.
If i can be of any further help please don't hesitate to ask 😎
