I tried everything you suggested but it did not work.
Last year the publishing house had decided to use Google fonts and the fonts included with the Adobe CC subscription exclusively in all their published material, including replacing all the fonts when reediting their bestsellers (which is what I’m doing at the moment). After a hellish weekend where things kept getting worse crashwise, I gave up and went to watch a movie. While relaxing, a word came to my mind: fonts… I rushed back to work, removed and redownloaded the Adobe fonts I was using and, well, ID stopped crashing, and I did more work in an hour than the whole previous day. And still not crashing today.
So, not sure it was the only problem, I keep my fingers crossed… and I decided to include watching a movie in my bag of tools when facing mysterious technical problems.
