Congrats!
If you used CEF 74.1.19 then you should use the last CEF4Delphi version that used Chromium 74 :
https://github.com/salvadordf/CEF4Delph ... 0.3729.157
The version numbers you gave are the answer : 74.1.19
If I'm not mistaken, the CEF branch and build are defined in some CEF constants.
Always use the RELEASE version. The debug version of the CEF binaries cause many issues.
