Hey - I've found 2 issues, and left some high level feedback:

• The query parameter handling for release, target, and arch (initializing state on open and cleaning them up on close) is now duplicated across multiple useEffect/helper blocks; consider extracting this into a small utility or hook so the behavior is defined in one place and easier to maintain.
• The large JSX blocks that build the Base settings and Advanced settings steps repeat the same pattern of conditionally rendering multiple substeps with dividers; extracting a small helper/component to generate these sections would improve readability and make future adjustments to step ordering or layout less error-prone.

**issue (bug_risk):** Reset `hasInitialized` when closing the wizard so create-mode setup runs correctly on subsequent opens.

Because the create-mode setup is guarded by `hasInitialized.current`, closing the wizard without resetting this ref prevents the initialization (including registration defaults and URL param handling) from running on the next open. Add `hasInitialized.current = false;` in `handleClose` so reopening the create wizard triggers a full re-init.

**issue (bug_risk):** Prevent default form submission on the base settings step to avoid accidental page reloads when pressing Enter.

On the other steps, the `<Form>` uses `onSubmit={handleFormSubmit}` (which calls `event.preventDefault()`), but the base settings `<Form>` has no `onSubmit` handler. This makes Enter behave differently here than on other steps and can trigger a native submit. To align behavior, wire this `<Form>` through `onSubmit={handleFormSubmit}` as well.

Can take a look at this in a separate PR, it's out of scope here.
