One channel keeps freezing with new cable box

Finally swapped out our old, large HD cable box for the smaller, newer 4K XG1v4 box about two weeks ago.

Recently noticed that one particular channel (local NBC station) keeps freezing and/or loses audio for 30 seconds-1 minute stretches.  Haven't seen it happen on any other channels or streaming apps as of yet which seems odd, but it's very annoying since it occurs multiple times per hour (every 10 minutes minimum).

Tried refreshing box several times, system refreshed 2 or 3 times, unplugged and replugged ALL cables (power, coax, HDMI) multiple times.  Checked signal strength as well, especially right after video/audio catches back up and it always shows green/good connection.

Why would seemingly one channel be effected and, more importantly, what else can I do to remedy this?
