This PR resolves the issue with updating the profile picture in the profile settings.
**Cause of issue**
The issue can be reproduced with the old `ProfileAvatar.vue` component.
While the exact reason is unclear, it seems related to cases where the
file might be `null`.
**Solution**
Replaced the old `ProfileAvatar.vue` with `Avatar.vue` and tested it. It
works fine. I’ve attached a loom video below.
