Hi I stored some conan in a kilner jar in the fridge for a few months, took it out to get ready for stepping up brewing, looked fine until today it has whitish film on the surface, anyone ever come across this , didn't open the jar or anything , took pictures here

I'd say LE might be right. I've had this on stored yeast before, albeit in a plastic container.

The yeast was unusable.

I threw it into a starter fook it, if it is mouldy when I need to pitch u have some us05

Was it a thin waxy film? If so, some of us have experienced this on cider. It might be a bit late, but you could try extracting the yeast from the bottom.

And then acid wash it as these film yeasts don't like the acid "up-them captain Mainwaring"
Remember: The Nationals are just round the corner - time to get brewing

You could use a pipette or similar, maybe gently siphon from the bottom.
