Thanks for the response . Test Complete version is 12.42.3048 and I have web module enabled
What version of CEF? According to https://support.smartbear.com/testcomplete/docs/app-testing/web/general/cef-support.html?q=chromium#about-automated-testing-of-cef-based-applications
"Currently, the supported versions of CEF3 builds are 3.2883.1553 and earlier. If you use, NuGet or some other package manager to add CEF libraries to your application, make sure that the version of the CEF build within the package conforms to the version of CEF builds supported by TestComplete."
Thanks again. I am not sure on the CEF version, but the version of dotnetchromiumbrowser is: 55.0.2883.87 (https://www.nuget.org/packages/DotNetBrowser/1.11.1)
