As for the record theirs no mining pool who stop operating since the last halving as for the individual miners and pool participants, there's no record about that so we can't tell.

If you're concerned on the profit they will get, in this last block mined ^[1], it's total profit is 6.112BTC (block reward + accumulated tx fees). So miners getting scared of having enough profit is not that crucial as it only lesser their profit in small amount.
