Why does Nucleus+ go on strike?

That is a seriously LARGE collection and will take even a blisteringly fast PC a long time (many days) to import. I have ~ 25,000 and it takes a long time on i7-7700 8 core setup. my database is already 20GB so a 64GB system/boot/databse drive will be too small perhaps if it really is 100,000 albums you have

If this is a new setup be prepared for at least week maybe longer if your files are on a NAS
