Version `3.0.1` not loading properly

After installing v3.0.1m I'm seeing this:

ERROR in ./node_modules/react-collapse-pane/dist/react-collapse-pane.esm.js
Module not found: Error: Can't resolve '@mui/material' in CENSORED/node_modules/react-collapse-pane/dist'
 @ ./node_modules/react-collapse-pane/dist/react-collapse-pane.esm.js 3:0-49 172:8-12 173:8-12 174:8-12 175:8-12 476:51-55 482:36-40

 @ ./packages/core/src/components/SplitPane/index.ts

I uopgraded from v2, is there anything else I should do?
