HI @advdishant
Sometimes there can be conflicts with 3rd party apps/themes and if you have installed any lately an idea to run in Safe Mode, if problem does not exist in this Mode would pinpoint issue, https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/
However if not the case clearing the cache partition can help and is advisable after updates, if you have not done this recently. Cache files can be outmoded or even corrupt, this will delete the temporary files but your Data is intact. Follow these steps:
1. Turn off the device.
2. Connect To Computer , Press and hold the Volume Up key and then press and hold the Power key
3. When the Android logo displays, release both keys.
4. Wait until the Android system recovery menu options appear.
5. Press the Volume down key several times to highlight wipe cache partition.
6. Press Power key to select.
7. Press the Volume down key to highlight yes, them and press the Power key to select.
8. When the wipe cache partition is complete, Reboot system now is highlighted.
9. Press the Power key to restart the device.
Can also Repair apps from the same Recovery Menu.
