The NC instruction was accessing PSA (page 0 not subpool 0). PSA is such a critical system area, it has extra protection than just key 0 which is why you had a S0C4.
Why are you running in KEY0? Key0 is generally only needed for a short period of time so just set it when you need it. If you had not accessed page 0, it's likely that storage would have been overlayed. At this point, you can cause everyone grief.
