BTRFS check --repair not fixing the error. 24 hours deep

Installed 6.9.1 and added my unassigned drive into a pool that was already formated with BTRFS and had data on it. Came back the next morning to find the drive read-only and BTRFS having multiple errors.

Tried running 

btrfs check -p --repair /dev/sdd1

It seems to have fixed 1 of the errors but another file is still trying to be fixed 24 hours later.

Is there any way to just delete that block or file and replace it manually. The drive holds a backup of my array, and I really don't want to loose my snapshots and have to copy 8TB back onto it.

Here is syslog when everything started going downhill:

The other screenshot is the log from "btrfs check"

    btrfs check --repair should be use with much care, there's even a warning about it when you use it, and it can make things even worse, probably best to try and recover the data and then re-format, if still possible.
