Inability to use MUI icons and react-router vite plugin

[mikezx6r]

I'm using React Router as a...

framework

Reproduction

https://github.com/mikezx6r/react-router-mui-icon-issue

Start the app with the 'Check' icon present. Error as per screenshot.

Comment out 'Check' and app renders as expected

I will also be filing this on the MUI site, and will update with ticket # from there

Should have searched MUI first. This may be the same issue.

My apologies. Reading further, and it definitely appears to be a MUI issue. I will close this issue.
