Omnisharp does not allow selecting files to analyze

[Ceeemon]

After the update I am getting this problem:
Extension 'ms-dotnettools.csharp' CANNOT use API proposal: quickPickSeparators.
Its package.json#enabledApiProposals-property declares: [] but NOT quickPickSeparators.
The missing proposal MUST be added and you must start in extension development mode or use the following command line switch: --enable-proposed-api ms-dotnettools.csharp.

I have not changed anything, other than updating.

This seems to be introduced after updating to vscode 1.63. I'm having the same issue since updating too.

This breaks working with omnisharp in a monorepo for me.
