Sorry, I was in a hurry and didn’t add the artists correctly. Now I’ve added all the artists. What I learnt is I shouldn’t attempt to rush adding any releases but instead take my time. No errors now.
I’ve finally added the release without any errors: https://musicbrainz.org/release/18260481-5567-4f8d-983f-c732a57a68fe
If you have any feedback it is welcome. I did make a spelling error where track 1 got Zero Gravit. I attempted to correct it by adding a ‘y’ in the end. I think it got added.
