Newbie wondering why GBPUSA dropped so fast

I’m wondering if anyone knows why GBPUSD dropped over 30 pips in 10 seconds this morning at 03:30 ET. I was doing fine and then it dropped and stopped me out. There was no news that I can find.
Then I see that comes all the way back up in the next 1/2 hour.

Almost seems like it was manipulated to stop everyone out. I thought that couldn’t be done in the Forex.
