I didn't included it here, it's very simple, any access to that file shows it

$ cat system@00051e80d8810e86-e5a1ec29d9167e9f.journal~
cat: system@00051e80d8810e86-e5a1ec29d9167e9f.journal~: Input/output error

even if scrub completed successfully without any errors.

also I just noticed this thread
"btrfs partition fails to mount - kernel BUG at ../fs/btrfs/extent-tree.c:1872"
it's this same crash I'm hinting here with balance.

kernel: kernel BUG at fs/btrfs/extent-tree.c:1872!
