Resolution:

Approach #1

Open the impacted project and uncheck the Separate Runtime Dependencies

Retry the Publish from Studio

Approach #2

Close any Studio windows -> go to %Studio_install_dir%\UiPath\Profiles\Development.json and change EnableProcessSplitToDesignAndRuntime from true to false

Open the previously impacted project.

Retry the Publish from Studio
