When I run zfs destroy -r zroot/swapdisk0, I get: > internal error: Numerical argument out of domain > Abort trap Dear Ludovit, I am running out of ideas. swapinfo shows no use of swap?

If that does not work you might have to boot from a different medium as the USB installer stick and handle the pool when it is inactive.
