Does anyone have a good tutorial of how to set up a ColdCard wallet to use with BTC Core? I have been having issues setting it up.

I had to reinstall BTC core after my old harddrive crashed.  I got a new hard drive.  When i download bitcoin core, after it synchs anywhere between 30-60% of the blocks, I keep getting the error message "error opening block database. Do you want to rebuild the block database now?".  I click  yes, but then it says "error opening block database" and it won't allow me to download more blocks.  How do i fix this?
