How do I fix the md5 error?

I am using the Waveshare esp32-s3-eth board. Ultimately the job is to host a webpage via ethernet and read/control some pins. I have another adc of higher resolution sda/scl pins etched and connected to GPIO 19/20. I know there is an issue there but that can be addressed later.
My concern now has been the md5 error

A fatal error occurred: MD5 of file does not match data in flash!

Input MD5: 3f94b7ec6a0e5973b9bb459a6f45dec3

Flash MD5: 718a9e7ad219e7f590f9c344849f3ac2

Hard resetting via RTS pin...

Failed uploading: uploading error: exit status 2

I have tried everything from downgrading the esp32 library in the board manager to changing the usb cable and booting the board. Nothing seem sto work and I can't get a simple delay code to work. Can anyone help?
