I've migrated 11 projects from server, 2 of which are inaccessible

When you say you migrated them, did you migrate them from server to cloud using JCMA? Are these team-managed or company-managed projects?

I found other articles indicating cross-project boards can break the view, I've found one I suspicious of, but I can't edit it.

p.s., they are all company managed
