Hi there 👋 and welcome have you tried it in safe mode ? If so try to disable all bixby routines, then other possible solution is to reset network settings, if nothing works try to do wipe cache partition to do so turn off your phone connect to PC, macbook etc then press and hold power and volume up button until samsung logo appears then quickly release power button and keep holding to volume up until reboot menu appears then with volume down button navigate to wipe cache partition and press power button to confirm and restart your phone see if that helps
