Track stops playing no reason cubase 13

A track on my project has stopped playing for no apparent reason. The bar doesnt move and playing the track with the play tool does nothing. Also tried making a new track, no luck. What is the fix/cause ?

Hi,

Try to click on the Deactivate All Mute States button, please.

Make sure, the ASIO driver is selected and setup correctly and the Buffer Size is set to a meaningful value, please.
