I've carried out simple tests with DBW 1.71 and some mods and found the following -
1) all carrier mods off = game loads, CVA-19 loads, wings fold, no catapult
2) CTO 5.3.3 = game loads, CVA-19 loads, wings down, no catapult
3) SAS AI Engine HotKeys Carriers = game loads, CVA-19 loads, wings fold, catapult OK
4) !SAS_Engine_Mod_4101m_v26 = game loads, CVA-19 loads, wings fold, catapult OK
5) (2) + Rawners Essex crew = game loads, CVA-19 loads, wings down, no catapult
6) (3) + Rawners Essex crew = game loads, CVA-19 loads, wings fold, catapult OK
7) (4) + Rawners Essex crew = game loads, CVA-19 loads, wings fold, catapult OK
I recommend the !SAS_Engine_Mod_4101m_v26
https://www.sas1946.com/main/index.php/topic,23327.0.html. It is a collection of over a dozen related mods which alter engine behavior, add additional hotkeys, carrier features, new aircraft features and tweak the default AI routines. An additional entry for the Hancock is needed in catapult.ini.
Another possibility of reason for crashes is the name of the carrier. Check that "USSHancock_CVA_1970" - not "USSHancock_CVA19_1970" - is used for folder names and other entries as advised in the readme.txt.
I'll help as much as I can; keep trying, there's a lot of work in this ship.
