It seems like older versions of the fluientUI library require React16, which is the error you are hitting as you are running React17.

I have a project which uses react 17 and was able to install the following versions:

"@fluentui/react-icons-northstar": "^0.64.0",
"@fluentui/react-northstar": "^0.64.0",
