Other comments

In a way larger project, we require the use of declarations. Furthermore, do to deployment schemes, we do not use the unplugin-vue-components/vite in our vite configuraion, and thus require an import of the veutify components.

If used with defineComponents syntax, which almost all of our code base is, this will throw the above mentionend TS error as of vue ^3.5.0. This seems to work as expected using a setup script.

This may be related to this: vuejs/language-tools#1232?

I hit this with something as simple as just using VForm on the type of the the submit event callback, it seems that we have an un-exported SubmitEventPromise in vuetify/lib/components/index.d.mts, and an exported one in vuetify, which is indeed wrong and is what causing this error. This is likely coupled with some change in the Vue template compiler that was done at some point which then triggers this error.
