If you upgrade platforms you can't build new ones. It says no slots available, but there are free slots.
It seems upgrading platforms counts like building new ones for the available slots of a Starbase.

- Xbox Series X

4. When did this start happening?
- Noticed it after installing Patch 5.0
5. Can you replicate it, if so, please explain how

6. Does this happen on all saves or just specific ones?

7. What steps have you taken to try and solve this yourself (reinstall, Google error code etc)?
