Cache pool failed SSD, recovery issues

Need some assistance with a failed cache pool recovery

SSD1 of 2 failed.

Have taken the array offline, set to 1 device and attempted to restart array. Got a 'unmountable no pool uuid' error.

Tried a 'btrfs rescue chunk-recover -v /dev/sdb1', now I get a 'unmountable: no file system' error

Is there still a way back to recover the data, or even mount the former btrfs pool pair?

Any help appreciated.

    There are some recovery options here, note that because of a bug if the pool was created on v6.7.x it will be non redundant.
