The game boots to a black screen most of the time. There are some exeptions where the game reaches the main menu and the mission selection screen, but as soon as a mission is selected it crashes. If I have to give an estimate, this happens 1 out of 15 tries.

I couldn't copy-paste any error messages since the console gets dragged in the shadow realm with the game when it goes down.
If anyone can tell me how I can get them, please let me know, I'd be very excited to play this game again.

shadPS4 has a logs folder you can get the errors from.
If you're using the Qt GUI version, open shadPS4, right click on your game, and choose Open Folder -> Open Log Folder.
If you're using a command line version of shadPS4, then you need to manually navigate to the shadPS4 log folder (should be something like C:/Users/username/AppData/Roaming/shadPS4/log on Windows).
In there, there should be either a shad_log.txt or a CUSA00062.log file containing all the errors (depending on your shadPS4 settings).
