VS 2022 launching a non-experimental instance

[benblo]

Title pretty much says all: I just installed the VS SDK, followed the first simple tutorial (Create an extension with a menu command), but when I press F5, instead of the experimental instance a regular instance is launched (without my extension/menu command).

I then tried installing the VSIX community essentials, and followed another tutorial, same effect.

I manually started the experimental instance (devenv /rootSuffix Exp), and both extensions are there. But launching from VS still doesn't work.
I also tried manually adding /rootSuffix Exp to the start arguments in the project settings, it doesn't work and the arguments actually are wiped as soon as I launch.

I also tried resetting the experimental instance, no change.

Ideas? I'm VS 2022 Community, could it be a restriction of the community edition?

Hey I am the co author of the Smart Command Line Arguments extension stumbled upon this issue by accident.
I think the issue you are encountering comes from our extension.
The last update (v3.2) should fix the issue because with this version, the extension is disabled per default and you can enable it on a solution basis.
If you have our extension active it manages the command line args and if it has none configured it removes the existing arguments.

There are several solutions:

• Add the the /rootSuffix Exp arguments to the list in the extension window.
• Update the Smart Command Line Arguments extension to at least v3.2 (the extension should be disabled by default then) and add /rootSuffix Exp to the start arguments manually for any existing solutions. New solutions should work as normal as the extension is disabled by default for them and even if you activate the extension I should copy the configured arguments into the extension.
• Uninstall the extension and add /rootSuffix Exp to the start arguments manually.
