My watch keeps vibrating when I receive a phone call and won't stop vibrating even after I answer on my phone

The watch won't stop vibrating even after I answer on my phone and if I hit the red button on the watch the call hangs up. 

If I restart the watch or the phone the problem is temporarily solved ,only to return again. 

P.S. I am using an Android phone Samsung S24 ultra with the Garmin Venu 3
