Could you please update the Uiautomation package and try. For your reference please check below thread.
Did you get it to work? If not, a full reinstall would be advised, with clearing of all the folders from here:
I hadn’t solve it yet, I’ve found a pattern on when it occurs and how to bypass it, basically it happens when I open uipath with one internet connection, and I pass to other connection, before restarting my PC, even though I had closed uipath, it even happens when I switch from Ethernet to Wi-Fi or vice-versa on the same connection, and will only be solved if I go back to the first mean of connection, or if I restar the PC.
I will do a full reinstall and give update, thanks.
Could you provide a screenshot of your licencing from Studio -> Help?
Also, a full log of that error message could potentially help (Copy to Clipboard and then paste here).
