the CHROMA_DB_PATH is deleted in the latest assets, please add this line at the end of assets/init.py for temp solution:
CHROMA_DB_PATH = ASSETS_PATH_ABS / "chroma_db"
and create an empty chroma_db directory in assets root directory.

This will be fixed in the next update

Thanks, the import issue has been resolved. What caused problem 2?

this is because the output log is not in the form supported by mcp, it can be ignored.
