Hi... when did start to happen? It is after a security update? 🤔 Anyway,
First, Go to Support tab of this app and select Diagnostic > check Sensors and proximity sensor whether it working normally.
Then turn on your device in Safe mode. (You can check on Google if you want to know how to turn on the device in Safe mode) It'll allow you to find out if the issue is happening due to a bug in an app you installed.
If the issue is still there even in safe mode, better to reset your device. If not resolve the issue after the reset, then probably it's a hardware issue. Visit a Samsung service center for assistance in such case.
