Hello,

My project is working fine, I can compile and run the package in my sandbox but when I try to use the feature F6 in order to run the Business Central in mode Designer I receive this error message.

    This indeed was a bug and is fixed in the current prerelease version of the AL Language extension: v12.0.800702.

    We no longer need to get the next AL Language extension version from preview containers, now they provide this directly through pre-release versions of the extension in VS Code

    Hi, same here, I suspect this is a problem with the standard.

    I have installed these extensions but still received the error message when I try to run the "Command Palette" -> " AL: Open in Visual Studio Code Designer".
