I am reposting the Forum post below that was posted by @Heena_Saini. I did not see an answer. Today is 2/26/2020. I just began to get this with both IE and with Chrome. I am using 2019.4.4.
@lakshman posted that this was a possible solution. However the second item to solve things is to uncheck “Enable Enhanced Protected Mode” which I will not have rights to do. Is there another solution?
I would appreciate any assistance you can provide.
Chrome displays this AFTER successfully attaching by the way.

I will have the Chrome extension uninstalled @manishjagtap. See my response to @Pradeep_Shiv a moment ago. I had built many automations targeting IE. No problems. I was trying to assess performance so I had the group policy on the PC updated and the Chrome extension installed. After that, I was getting the “Cannot communicate with browser…” error on both IE and Chrome. I will have the extension uninstalled and verify the results. Thanks very much to you both for your followup.
If you are working in a server environment and cant disable enhanced protected mode, that will be a no go for IE for sure, also maybe your network is preventing you from using any browser extensions, please make sure this is not the case as well.
