The creator companion seems to have a really hard time with massive projects.
In the pictured example of "AV3" (a large but not huge example), it eventually stopped hanging, and moved onto the pictured migrating screen, but it might be ideal to thread or offload the migration process to the background so the application doesn't get inadvertently killed while setting up.
I'll post an update to this ticket after testing Vket 6 Core
