Any additional comments?

I tested both vue-tsc@2.0.29 and vue-tsc@2.1.6, and encountered the same issue in both cases, leading me to conclude that the problem lies with Vue rather than Volar.

I downgraded Vue to version 3.4.38, and it works now.

Perhaps this issue is also related to volar.

It seems that this issue can't be reproduced in Vue 3.5.3 + Vue extension 2.1.6.

I updated the mini repodunction.

can't reproduce

Why ? I think the type of onUpdate:open should be (val: boolean)=> void.
