2023.8.0 Core Update Broke Configuration File

I am operating Home Assistant on a raspi 4 - 64 bit, I recently update my Home Assistant Core instance. As soon as it restarted I was greeted with error after error regarding my configuration file and I am unable to locate where the config file is having the issue. I tried recovering from a full backup, however when I do my HA instance just hangs and never fully reboots, I have to unplug power and start back from square one. I have either disabled or deleted all instances of custom integrations from HA just to make sure that it’s not something regarding an incompatibility issue. I have attempted ‘Repair’ but it tells me that there is nothing wrong, however I cannot Restart HA due to a config file error, I can however Reboot.

Line 2 is the error that is popping up, discovery integration error.

Here are my log files, hopefully someone will be able to point me in the right direction. Thank you.

Listed as a breaking change in the release notes

yep i found it, thank you for point that out.

Discovery

The legacy discovery integration has been removed. This only affects the automatic discovery of Enigma2, Yamaha Network Receivers, and Bluesound.

These can still be manually configured as per usual.

Note this is for our very, very old discovery logic. This does not affect the discovery of any other integration/device/service.

If you still have discovery: listed in your YAML configuration, you can safely remove it.
