Bun Crash on Windows: panic(main thread): Internal assertion failure

[vgseven]

How can we reproduce the crash?

I don't know exactly how Crash happened but, While running Next.js 14 application created using bun and running using bun --bun run dev server crashed when I forget to enter argument to Link tag of Next.js and saved it.

JavaScript/TypeScript code that reproduces the crash?

Missing tag in Link.

<Link>signin</Link>

Relevant log output

Bun is crashing when bun --bun run dev is used, means bun crashes in bun environment only not in node.
