Tech Support Windows 11 Insider 25H2 (Build 26220.8764): Multiple Chromium/Electron apps crash unless launched with --no-sandbox
Hi everyone,
I'm on Windows 11 Insider Beta (25H2) Build 26220.8764 and I'm seeing a strange issue affecting multiple Chromium/Electron-based applications.
Apps that crash immediately on normal launch:
- Opera GX
- Discord
- Postman
- GitHub Desktop
- Comet browser (perplexity)
Temporary workaround:
Launching the actual executable with `--no-sandbox` makes all of them work normally.
Examples:
- Discord.exe --no-sandbox ✅
- Postman.exe --no-sandbox ✅
- GitHubDesktop.exe --no-sandbox ✅
- opera.exe --no-sandbox ✅
Apps that work normally without any workaround:
- Microsoft Edge (Chromium 151)
- Google Chrome (Chromium 150)
- Brave (Chromium 150)
- VS Code
- Spotify
- Steam
- Epic Games
- Rocket League
One interesting observation:
- Opera GX is still based on Chromium 149 and crashes.
- Chrome/Brave/Edge are on Chromium 150/151 and work fine.
- However, Electron apps like Discord, Postman and GitHub Desktop also crash despite being on newer Electron builds, so it doesn't seem to be a simple Chromium version issue.
Things I've already checked:
- SFC and DISM are clean
- Latest Windows updates installed
- No third-party antivirus
- No AppLocker/WDAC/IFEO issues
- Intel and NVIDIA drivers are up to date
Discord logs show repeated GPU process crashes during startup, but the application starts normally when launched with `--no-sandbox`.
Has anyone on Build 26220.8764 (or nearby Insider builds) experienced something similar? Any ideas on what Windows component or sandbox change could be causing this?
