@kcfinished you might have got a .local-chromium folder into your bin file. Inside you should also have got a chromium folder. Could you check if you are able to run the chromium app located on that folder?

@kblok this is from Debian Buster, but may help. Adding the --no-sandbox argument does indeed allow PuppeteerSharp to work for me with netcoreapp2.2 in debian 10 in headless mode to take screenshots.

Update your kernel or see https://chromium.googlesource.com/chromium/src/+/master/docs/linux_suid_sandbox_development.md for more information on developing with the SUID sandbox. If you want to live dangerously and need an immediate workaround, you can try using --no-sandbox.

Had the same problem, here's what I get if I start it myself

But running it with --no-sandbox makes it work.

Here's the fix

launchOptions.Args <- [| "--no-sandbox" |]
