Is there somebody knows the solution?

    Hi @Dango,

    Which browser are you having issues with?

    There's been some issues with the Firefox plugin as of late, and you may have to re-install it, See instruction here

    Thank you for your reply.

    I use Chrome. I also tried using Edge and Firefox. But it didn't work well.

    When launching browser, the PAD launches the browser without problem.

    But it can't create the browser instance.

    When I checked the instance on the left panel which is flow variables,

    the brwoser instance is still vacant despite the browser is launched.

    I also reintall the browswers plugin. But the problem hasn't been solved.

    And I try the same PAD process on another PC, then the PAD can create the instance when it lauches the browser.

    That PC's OS is not the latest one. And I guess after updating the OS to the latest, the PAD can't create the instance for the browser.

    I have the same issue. Before the 22H2 update everything worked fine with Microsoft Edge. After the update no connection can be established. Re-installed the browser extension already. Installed Chrome now, too. Same issue. Hope someone can provide a solution here.

    A click on the error message in PAD actually shows that there is an exception thrown, very similar one for Edge and Chrome:

    I have the same issue, with both Chrome and Edge extensions.  I have re-installed the extensions multiple times. I have restarted the computer. It started happening after the 22H2 Windows Update.  I have tried the steps on this link (https://support.microsoft.com/en-us/topic/error-failed-to-assume-control-of-microsoft-edge-chrome-firefox-c2a74ccb-2896-4f3a-bcc7-7fecf92c3137), but no luck.

    Looks like the new update to Automate has fixed it. I had the same issue but 2.26.00230.22312 works.
