That doesn’t look like condensation to me, i maybe am seeing things but at first glance that’s a very leaky roof.
I remember that VWs had a similar issue, the culprit was a blocked drainage channel – did you park under a tree at some point, could there be a leaf or sap blocking a drainage channel?
That car immediately needs to go into the workshop, even if it is condensation – there shouldn’t be that much water in there, and you’ll run danger of creating a rat tail of issues further down the line if that doesn’t get rectified.
