`IKVideoPlayer` crashes with `TypeError: Cannot read properties of null (reading 'BigPlayButton')`

Description

IKVideoPlayer crashes during Video.js initialization with the following runtime error, even in a minimal setup without Next.js or React Server Components:

Runtime TypeError: Cannot read properties of null (reading 'BigPlayButton')

The error occurs even when the player is not rendered (i.e. conditionally hidden via state), suggesting it is triggered by module-level side effects in the bundled Video.js code.

Stack trace

Reproduction

Reproduced on CodeSandbox in a minimal setup (no Next.js, no "use client", plain React).
https://codesandbox.io/p/sandbox/82s6st
Steps:

1. Install @imagekit/video-player
2. Import IKVideoPlayer from @imagekit/video-player/react
3. Render it in a standard React component
4. The crash occurs at runtime

Expected behavior

IKVideoPlayer should initialize without errors.

Environment

• @imagekit/video-player: 1.0.0-beta.5
• React: 19.2.4

Additional context

• The error is a Video.js internal issue — getChild('BigPlayButton') returns null because the control bar / child components aren't ready when accessed.
• The dist/react/index.mjs bundle contains the entire Video.js library and appears to run initialization code that accesses DOM elements before they are available.

Reproduce the crash using the linked CodeSandbox with a minimal React component, then inspect the initialization path in dist/react/index.mjs around the Video.js getChild('BigPlayButton') call. Trace when the control bar and child components become available; done means importing and initializing IKVideoPlayer without the null-property TypeError, even when the player is conditionally hidden.
