hi, welcome to the forum!
could you please upload the *.skse file with the same name (in a zip/rar/7zip/... archive) as well?
(I tried loading just the *.ess and didn't have any issues, there could still be some information stored in that file that makes your game crash)
one of these things is more likely:
- do you have a modded follower with you? don't know how well Amanda plays with that quest.
- or (at least) one of your mods creates this issue and leaves behind traces when disabling it (like loose script files).
I'd suggest unsubscribing/uninstalling them and then doing another Steam-check on your files (as you already did before)
hope that helps
