"Park assist blocked" Message?

2016 silverado 5.3 8speed

Every time I stop or start moving symbol that something is in front of me alarms/beepssnd once it said "park assist blocked"

See owners manual?

What's the cause?

Anyone else have this?

Only once did I have anything familiar to this happening and it was one of the sensors bin front got bumped back behind the bumper causing it to freak out...

Does it happen when it is wet out (raining) or snow? Mine does it all the time when cold with rain or snow. Took to 3 different dealerships and said it’s normal.
