Under-extrusion after a certain amount of successful layers?
This is partial answer and comment as it was too big to fit the comment section, it will be a proper answer once the question is updated by the OP.
What you call a weird spiral pattern is the result of under-extrusion. When there is under-extrusion, the resulting print is sparsely filled. The reason for this under-extrusion is most probably partial clogging of the nozzle, or an issue with the extruder itself. One explanation could be that you are suffering from heat creep, but the information you provide is not enough to explain this or any other solution further in detail. Clogging can e.g. be caused by retraction settings and/or temperature settings, without your settings it is a guess what this is actually causing this.

Looking at the print deteriorate the higher the Z becomes this is most probably a heat creep issue, so you print too hot with too large retraction settings.
