Hi @goel.saloni can you check, if there is multiple profiles are created in your chrom browser?

3

Hey Tapan, I have checked what you are saying, Only 1 chrome tab opens up when I start my process. Or Do you mean something else by “multiple profiles”? Pls elaborate

4

I mean do you have logged in multiple users in your browser? if yes then go to setting and set only one user to default that you are using.

OK got it now. I have only one user, same user is logged in chrome browser as well as UIpath studio

I tried updating my UIpath studio again, and got this:
UiPath update failed.
The update for version 22.10.0-beta.10400 failed.

Please collect the logs using the UiPath Diagnostics tool, selecting the Update Service besides all other logs and contact your system Administrator.

Updated my studio, to 2022.10.3, and converted legacy project to windows. This has solved the Browser issue in small code. SO closing this topic.
