Having issue with ERG and with trainer in General!

Since sometime prior to start training if i want to follow a program the “only” way to be able moving the pedal is to pause the training, then pedaling for little time and after that un-pause and ride.
The thing is getting worse since many time to be able to continue i shall switch off the ERG which is not controlling anymore.
If i run without thru a path no issue but riding on a training became impossible.
I have tried to pair the taring with different devices and result is the same.

What to do? Thanks!
