Which apps are we talking about here may I ask @Geguti21
In short no an app shouldn't uninstall itself however first go and use the search bar to look for the apps please.
First try a soft reboot by turning the phone off and on.
Look in Settings > Apps > Tp see if these apps still show.
If your using a 3rd party launcher then try using Samsungs own to see if that helps.
Try something similar to > Settings > Apps, Look for One ui home > Choose it , Clear storage and data.
This is a generic troubleshooting step > 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.
If I can be of any further help then please don't hesitate to ask. 😎
