As of version 1.014, I'm still encountering errors during runtime. Could you please help me look into this bug? @JSerFeng

Sorry for the delay, I checked the repro, turns out it was a HMR bug for both Rspack and webpack, I'm fixing it but it was tricky, I'm working on it

For the temporary solution is to disable splitChunks, you can achieve that by config like this

defineConfig({
  tools: { rspack(config) {config.optimization.splitChunks = false} }
})

You can try this version @rspack/[email protected], should be fine
