Hi,
This situation is similar to a case that I posted a month ago.
https://forum.developer.samsung.com/t/bluetooth-le-issue-after-security-patch-update-level-2020-11-01/9595
You may try to see if this works:
Settings -> Connections -> Wifi -> (3 dots on the top right) Advanced
Try turn off the “Hotspot 2.0”. Then it should be good to go.
Or you can try if “Reset Network Settings” helps or not.
Cheers,
Alvin
