3.0.2 works fine here, no CLAP issues, but I made an init patch in 3.0.0 and saved it in the user folder. Try the new release, if it doesn’t work:
Init patch in the CLAP version - it should just be a saw wave, then save this patch in the user folder, I named it Initialize.
Edit: just save the patch, Zebra 3 saves to the user folder by default.
