Record stops working

Hi. Hope someone can fix this bug. Am using Essntial 5.
All of sudden, for no reason I can fathom, pressing the record button doesn’t start recording. Only the record button lights up but nothing happens untill I press ‘Play’ - then recording de facto begins. It’s as if cubase has changed ‘record’ with ‘punch-in’. I can work around this usually, but it is very frustrating! Also, this means I get no precount bars, which makes eveything a mess.

Please help! Recording sessions ahead!

Thank you

switch off external sync…
