What can I do about condensation between double-glazed windows?

Hello all
I have found that I have two windows which have been developing condensation in between the glass panels.
Is this usual for double glazed windows?
As I have never seen this happen before, I had suspected that they may have a gap allowing for the water vapour to get in – is there any ways to fix this or at least keep the glass clean enough?
If this isn’t repairable and needs replacement – is there any causes that could prevent it happening again?

"If you have condensation between the glass (double glazing), it means your units have broken down, best to get a window fitter out to measure up for new units, he will need to remove a couple of beads to also measure thickness of glass.
Although some window firms have a device for this."

"Replace the units is the only option. Warm edge and argon gas are good for longevity of units"

"The good news is that you do not have to change the whole window and can just change the glass. There is no way of repairing the blown glass units that is cost effective so changing the glass is the best and cheapest option. I could give a clearer picture with more information and photos.

Kind Regards

The double-glazing glass units have broken down and the windows have blown. The glass will need replacing as it can't be repaired."

"You can replace the glass and have trickle vent in stalled to stop it happening again"
