Dependency issues upgrading to MUI version 5 - reactjs

Question

I'm trying to upgrade MUI v4 to MUI v5, and I've read the docs in migrating to v5 here.
I get this error message when running npm update
npm ERR! code ERESOLVE

Not sure how to fix this, it appears the log tells me that react#^17.0.0 should work and I'm running version 18.
npm auidt --production provides the following info:

Answer 1

Try to update your dependencies using npm-check-updates
https://www.npmjs.com/package/npm-check-updates

Answer 2

Turns out, I was not thorough in reading the MUI docs, I had to:
npm uninstall #mui/style
npm i #mui/system
replace old code that was dependent on #mui/style
This removed the version mismatch.
I tried different ways i.e npm update --force / npm audit fix --force which just made it worse by downgrading to different packages creating many more vulnerabilities.
Thanks all for the help! Will accept sancelots answer though I did not try it, it seems like a beginner friendly solution
