I attempted a fairly large high-quality cache over the two areas you listed (as well as the pattern around EGLC that tamalien posted above) and I still couldn’t get it to CTD. The only difference to your parameters was that I set the cache file size to 16GB, otherwise my SSD would get too close to full.
My guess is that the issue could be caused when the game is attempting to communicate to specific CDNs, and it might be worth using a VPN (several users have reported that this fixes issues like slow download speeds, looping packages and more). Not really sure what else could be causing this. It might also help to follow the official CTD instructions in here and here (the advanced steps seem a little much since this does not appear to be a user-specific issue).
