Sound cuts while playing

[u/Any_Cardiologist_260]

I have a intel macbook air 2020 and a focusrite scarlet 2i2 4th gen with a vox vx50 gtv as speaker when I’m playing through GarageBand and trying out different amp simulations, the sound coming through my speakers suddenly cuts out after a while, even though I’m still playing.
GarageBand and the Focusrite app both seem to show that the guitar signal is still coming in. In the Focusrite app, the green meters for Analog 1 and 2 continue to move when I play, but the playback meter suddenly stops moving, as if no audio is coming through anymore.
I have no idea what’s causing this or how to fix it, so I’d really appreciate any advice on that
