Hi,

Please update to the latest build and see if that resolves the issue for you. Internally EO.WebBrowser starts multiple child processes and communicates between those process through named pipes. It appears that you have multiple different versions of EO.WebBrowser running on the same computer and a process from one version connects (incorrectly) to a process from a different version. Because the data format exchanged between the processes changes from version to version, this caused a process to receive data in the wrong format.

Our latest build has fixed this issue so that process from one version won't connects to a process from a different version. So if this is the root of the problem, the latest build should resolve this issue for you.

Thanks!

Not just any EO.WebBrowser 2019. You need the latest build from our download page (19.1.81.0). Early 2019 builds still have this problem.
