Samsung S9 apps keep closing after 2 seconds!

Hi,
I have a Samsung S9 and recently had someone put their phone on top of mine.
After that my phone seemed scrambled or something. Apps keep closing merely 1 second after opening, sometimes 2 seconds.
It is on every app that I open at that point.
I have seen several solutions in forums, like updating apps and starting in recovery mode and clearing cache and rebooting. Nothing helps.
What can I do to solve this? And does anyone know if the phone is permanently damaged?
thanks for all...
