Please provide a minimal runnable reproduction.
If you are running the compat build in Vue 2 mode, then the parent that is using v-model on your component will listen for ìnput, not update:modelValue`.
You would have to deactivate the COMPONENT_V_MODEL compat flag in your app, or in that parent component's compat config.
