Post zip transfer, PC to Mac! need plugin

I get this message after I zipped the project on a PC to reopen on my iMac.
“This project requires the ‘MetaHuman’ plugin, which could not be found. Would you like to continue?
If you do, you will no longer be able to open any assets created with it. If not, the application will close.”
It has become a big project and my iMac has more power than my PC laptop. Any guidance would be appreciated!
