Hi @StarWarsFan11 and may I extend a Warm Welcome to the Samsung Community Forum. 👋
If the restarts are random so at not exact times then the setting that allows a set restart shouldn't be the issue.
Here are a few first troubleshooting steps >

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 }
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.
As a very last resort back up and factory reset and then set the phone up but dont use the back up. Set it back up manually.
If i can be of any further help please don't hesitate to ask 😎
