Unity/SDK Validation error

I’ve uploaded an avatar successfully for PC and Quest so it’s not cross platform however I needed to make some changes and update it after the fact but now this bug plaguing me all day is back.
The validation in the build section is not showing and I’m being bombarded with errors. I’ve reinstalled the VCC, Unity, re-loaded the SDK several times, I’ve re-made my project several times and I’m tired of having to do so. Note that I haven’t made any changes to my avatar of yet so it’s in a working order as last uploaded, please help. I also want to add that the error codes don’t show up until the SDK Control Panel is open and once on the Build Tab it starts to flow in, if I close the control panel it stops.

This is my Error Code:

Don’t try and make sense out of the bottom half, focus on the top half on the console tab. Null reference makes no sense? Look at other messages. You don’t need to care about what line of code is complaining

yknow it wont let a person upload with this error
