Oculus Quest - Gesture and grip/trigger buttons are not working

When I play Half-life Alyx using ReLive I'm stuck with the default, "open hand" (see attached). Pressing in the trigger or grip button does nothing, nor does the finger tracking with the thumb or index finger. It does work properly when

all I did was press the grip button this morning and the mechanism that allows the button to pop back out came loose and is now obstructing my trigger. : r/oculus
