same here although i do have a lot of mods installed so thought maybe it was a conflict with one of them.

so i removed everything (except the squad folder of course) and added each mod one by 1 till the problem appeared again. once i installed planetary base the problem returned.
so I again removed everything except for squad and planetary base and the problem is still there.
as soon as i remove planetary base I can do crew reports and science experiments again.
its a shame because i really love this mod.
