I encounter one issue for several RPAs lately: Cannot communicate with browser - please check UiPath extension. This happens for both Chrome and Edge. I use UiPath Studio Enterprise.
What have I done trying to solve, but without success:
reinstall Chrome & Edge
reinstall extension & enable it ( I have tried installing for Current User, Group Policy Online - none of it works)
As far as I remember we had similar error happening when some members of our team were using their own profile in Chrome.
Robot would then open Chrome in guest profile and it’s impossible to run automation of windows when more then 1 profile is opened.
However I don’t remember how we ended up solving this in the end.
