I have a cube with carbon frame, for the last 3 rides its started a cracking noise at the same area you mention. Honestly, there's no play in the head stock and no notchy feeling in the bearings. I dropped the forks and regreased the lower and upper bearings after a clean and the noise has gone.
Incidentely they were still well greased but the job cured my noise. Drop the forks and re do ?

have you just checked the bar clamps? loosen, clean and a light grease up could be it..
BTW, mine does the same when I accelerate hard and pull on the bars.

Sorted the creeking at the head stock stipped and greased head bearings but still have a creek from the motor ??‍♂️
My motor creaked like crazy after replacement. The two rear mounts hidden behind the cables just in front of the chainstay linkage were both not torqued so when I nipped them up the creaks went away. Make sure you have an accurate torque wrench or calibrated elbow when checking the motor bolts as they can snap if over tightened (18Nm).

Grease the shit out of every single joint, bolt, bearing and torque it to spec. It should go away if the frame is not cracked. Don't forget the pedals and headset.

Mine did the same exact thing after motor replacement but my problem was deeper. Removed the motor and found the two nuts for these rear bolts were installed improperly. I initially tightened them like you did but creek was back after a few rides. Picture shows scars left behind after I removed the nuts.
Over 200 miles now and creek is gone!
