Hi,
I am running somewhat similar mods as you and I occasionally get a freeze when trying to perform a science experiment too. Like you, I'm able to put the same vessel in a different game and it works, and I've been able to go back to past saves and I don't run into the same freeze doing the same science experiment on the same ship that results in the freeze.
I haven't tracked it down yet but I've tried removing [x] Science and some of the science related part mods I had experienced the hang on. I've gotten the freeze on a Crew Report more recently. That is odd. I am currently testing my setup without ScienceRelay installed. That's one thing I am thinking, aside from Ship Manifest, that might kick in when I click the "do science" button. Or it might not be a mod at all.
But to possibly trim culprits down, here are the mods that we share from your list.
