• Does this problem also occur in the CEF Sample Application
  CEF sample working perfect without problem.
  cefclient.exe --multi-threaded-message-loop --no-sandbox --disable-site-isolation-trials

• CEF sample working perfect without problem.

You'll need to test with https://cef-builds.spotifycdn.com/cef_binary_92.0.9%2Bg847fba0%2Bchromium-92.0.4515.51_windows32_beta_client.tar.bz2

If that crashes then please test with https://cef-builds.spotifycdn.com/cef_binary_92.0.14%2Bgadd734a%2Bchromium-92.0.4515.81_windows32_beta_client.tar.bz2

I haven't had a chance to upgrade master to the latest CEF build yet.

Crashes in libcef.dll are rarely bugs in CefSharp. Your likely comparing two different versions of CEF.

[netmaxik]

I did test and it all working in new version, I did download and test

[amaitland]

Does the problem reproduce in the current supported release (91.1.211)? Is there a reason you are building master?

It's still unlikely this is a bug in CefSharp, most likely a difference in settings. You'll need to download libcef.dll.pdb and get a proper stack trace. See https://github.com/cefsharp/CefSharp/wiki/Trouble-Shooting#loading-native-symbols-for-easier-diagnosis

[netmaxik]

91.1.211 same issue.
last working : 90.5.70-RCI4015

[amaitland]

Are you using the official Nuget package for testing? Please confirm the problem reproduces using https://github.com/cefsharp/CefSharp.MinimalExample

last working : 90.5.70-RCI4015

This is a nightly build. Have you tested with the latest stable version 90 release?

You'll need to get a stack trace as detailed above.

[netmaxik]

Sorry for long answer..
https://github.com/cefsharp/CefSharp.MinimalExample - I did test and all working perfect.

[amaitland]

What features is your application using? RequestHandler? JavaScript Binding?

You'll need a stack trace to get a better understanding of what's going on.

[netmaxik]

In this case Just open second windows. RequestHandler and JavaScriptHandler default.
