After vue update, vue-tsc generates: "TypeError: (0 , language_core_1.buildMappings) is not a function"

[crystalfp]

Vue version

3.4.30

Link to minimal reproduction

none

Steps to reproduce

Go to any Vue + Vite project and do npx vue-tsc

What is expected?

Before the vue update from 3.4.29 to 3.4.30 vue-tsc gave no error

What is actually happening?

$ npx vue-tsc

Any additional comments?

The issue has been opened also against vue-tsc, but its version has not been updated

Yes, I am facing the same issue even when scaffolding a new project with create-vue

I think this will happen if running @vue/language-core<=2.0.21 with @volar/source-map>=2.3.1 (not related to vue's version). Upgrading vue-tsc to the latest v2.0.22 seems to work fine.

Problem seems solved when updating vue from 3.4.29 to 3.4.30 and vue-tsc from 2.0.21 to 2.0.22

Solved with vue-tsc 2.0.22
Thanks a lot!
