Unattended flow giving error that doesn't in my computer

Hello everyone, I have a desktop flow that works as intended in my computer, we have a VM to run it unattended and the flow starts off running well but then it always gives the error "Argument 'BrowserInstance' must be 'Web browser instance'. ".
But when I run the flow on my computer there is no error there, why is that and how can I solve it?

    Hi
     
    If you are running it on a VM, are you running it logged in as someone???
     
    It thinks that essentially its unattanded and cannot launch/run an actual web browser

    Hi, 
     
    Try adding a retry in that action, I've encountered this same error before, and fixed it that way, or just send keys Ctrl + Shift + W to the web browser window, in my opinion send keys is more reliable. 
     
    Hope this helps. 
    Anthony.
