### 💻 Code

```ts
type SubTup = T extends [
...(infer C)[],
...infer B extends [any, any]
] ? B : never;
type Trigger = SubTup<[1, 2]>;
```

### 🙂 Expected behavior

The compiler should not crash.

### Additional information about the issue

I noticed that while PR #63014 fixed some crashes related to variadic tuples, the compiler still crashes (ICE) when using a slightly different syntax.

Reproduziere das variadic-tuple-Snippet aus dem Playground-Link oder im Compiler und verfolge dann den Stack durch built/local/_tsc.js, insbesondere durch inferFromTypes und inferFromObjectTypes. Vergleiche den verbleibenden Fehler mit PR #63014; abgeschlossen ist die Aufgabe, wenn das Beispiel nicht mehr den aliasSymbol TypeError erzeugt oder den Compiler zum Absturz bringt.
