Hello gwitley,
If you're still experiencing issues, and have access to the original file(s), you may try loading them to an external drive, and then move them from there to the Mac. That can help to rule out any possible conflicts with the current storage option used.
Be sure to also check for any available macOS and GarageBand updates to ensure the latest fixes/improvements are applied: Update macOS on Mac - Apple Support
For reference, the current latest version is macOS Ventura 13.0.1:
1. From the Apple menu in the corner of your screen:
•Choose System Settings. Then click General in the sidebar, and Software Update on the right.
•Or choose System Preferences. Then click Software Update.
2. If Software Update finds new software, click the Update Now or Upgrade Now button to install it.

3. Enter your administrator password, if asked. During installation, your Mac might restart, and you might see a progress bar or blank screen several times.
If you still have issues, you may try reaching out to the Apple Support Advisors that specialize in GarageBand here: Apple Support
If the issue seems to be isolated to Google Drive then this link can help with receiving support there: Google Drive Help
Cheers.
