Please provide the following output:
# btrfs ins dump-tree -b 38884884480 /dev/sda4
I'm not sure if it's an really invalid case or a false alert I haven't
found.
For the workaround, just like Nikolay mentioned, reverted to older
kernel and remove the inode by:
# find <mnt> -inum 45745394 -exec rm {} \;
Thanks,
