Thank you for contacting 505 Games Customer Support.
It seems that the game is not fully installing via the physical disc copy, we are aware of this issue and it is currently being looked into.
As a workaround, please delete the 17GB that the disc installed, go to the Control base game in the Xbox store and install the game from there (keep the disc in the console and the store will allow this). This should cause the full 42.07GB to begin downloading and will hopefully work once fully installed.
Please let us know if this works as most players who are experiencing this issue and followed these steps ended up resolving the issue.
