Variable inspection is broken for some typescript files when plugin is used (electron/chromium)

[mulgurul]

Hi

I'm using this great plugin in an Electron app build using react 18.2 and typescript build on an older ERB template, but upgraded several times.

When debugging inside Chromiums devtool then on some typescript files I can set breakpoints and they are hit, but absolutely no inspection is possible when paused on the breakpoint.

Removing the plugin fixes the issue, but then no fast hot reload.

I think I'm on the correct versions:

"@pmmmwh/react-refresh-webpack-plugin": "^0.6.2",
"react-refresh": "^0.18.0",
"webpack": "^5.98.0",

I'm using node v24.12.0
Electron version is: "electron": "35.5.1"

Are anyone else experiencing this problem?
And anyone has a suggestion to how to troubleshoot it further?

Thanks
