MUI: The TreeView component was moved from `@mui/lab` to `@mui/x-tree-view`.
You should use `import { TreeView } from '@mui/x-tree-view'`
or `import { TreeView } from '@mui/x-tree-view/TreeView'`
More information about this migration on our blog: https://mui.com/blog/lab-tree-view-to-mui-x/.
@PontusA - I can reproduce this tree view issue. Unclear how this broke in this version as it was not changed. That said, 5.5.0 does use the new package it suggests in the error. I’ll see if we can continue to use the lab package for 5.4, and if so, release a 5.4.5 with that fix.
@mikedhanson - No. This was fixed in 5.5.0 and will be included there.
Yeah strange, maybe React pulled the plug on the old library at the same time somehow?
If there is a way I can patch this myself thats OK also. I tried a far fetch solution with invoke-udjavascript in the header with the import haha, sadly didnt work
