[vite 4.4] Failed to resolve entry for package "csstype". The package may have incorrect main/module/exports specified in its package.json.

It works well in 4.3.x

Since upgrade to 4.4. Typeonly package like csstype, throw the error:

The package may have incorrect main/module/exports specified in its package.json.

I solve the same issue by:

1. ensure using import type ... from "csstype"
2. migrate "csstype" to 3.1.2
3. migrate vite to 4.4.11
