NOTE: This is not my own pic, but it's exactly what happened to me...
My Case: CORSAIR GAMER 4000D AIRFLOW BLACK
My MB: MPG Z590 GAMING CARBON WIFI
I connected it back very careful and frontal USB is working normally.
Now my question is, what to do so this not happen again, because i still need to change my MB, the blue part of the connector is not attached any more (glued) to the rest of it, if i try to disconnect it again, i'm pretty sure the same will happen...
