Insulate exterior wall before the cladding is in place?

[PZ67]

Building an attafallare, externally clad in gypsum with taped joints, where no studs are present. The roof is covered with a membrane. Now the delivery time for the outer panel is longer than expected, as we have chosen larch panel. Wondering if it's a risk to start insulating the walls to proceed with the interior? Advice is gratefully received. Regards

We had the exterior gypsum on parts of the house for a year before the paneling was installed.
